- Fischer to Haworth Projection: This video gives an elaborate explanation on how the cyclic Haworth projection is formed from the open chain Fischer projection for both galactose and glucose. More specifically, it builds from the old presentation and comes into its own at 3min 10 seconds giving an elaboration on how (and why) the OH group on carbon 5 bonds with carbon number 1 as opposed to the OH from the 6th carbon. The presentation also explains how to label alpha and beta anomers for both D and L glucose and galactose while also proving a range of examinable questions with model answers. Enjoy :-)
By God, the Most High, the Great, you, professor, deserve millions of likes because of this great explanation, the idea of which thousands of teachers were unable to convey.
I was struggling horribly with this concept. Never have I felt more able to learn a concept that I have taken hours and hours looking into previously than this. Now every monosaccharide seems to be a breeze when converting to the Haworth projection! Thank you!
Thanks Ben 🙂
I was getting confused in these structures even after studying 'em 3 times from my biology textbook (Chapter Biomolecules)......after watching ur easy and awesome explanations I won't forget them anytime soon!! Thanks a lot Sir!!
Your comment made me choose this video ❤ Thanks

totally the best video about Fischer and Haworth Projection currently available on youtube, thank you so much
thanks!
totally I agree. and no smart talk like other videos try to make chem sounds so complex and enjoy audience suffering something only they know better or explain the unnecessary. this one just facts right to the points and critical clarification that test taker needs to know.
Thank you
I could cry. I finally think I understand this idea. Thank you so much.
Thank you for this video, it help me a lot to understand this.
no worries :-)
Where has this video been all my life!!! I need more of this in all subject areas. Thank you soooo much.
So well explained! Love the animations you used to showcase the reaction mechanism
Glad you liked it!
this is the best explanation of converting fischer to haworth i have ever listened to. thank you so much!
i’ve been watching videos on this all afternoon long but i knew when i saw yours that this was the one haha. thank you for explaining details that are often left out, such as what atoms change their places during the switch to the cyclic form and with what motivation, why it has to be the fifth carbon atom reacting with c1 and why on earth the substitutes on the left have to go on top. will be sending this to all the chem students in my hear. thanks for making this
Hi Chiara, thank you so much for your positive comments. It means a great deal to me. Thanks once again!
I have a very important exam of my life on 3rd October ( the Jee advanced) it can almost make life...
The video helped me a lot..
Love from India
Before ,I used to choose videos based on views and subscription . But this tutorial changed the way of my perception . Crystal clear about this topic . Thank you for teaching with minute details . Subscribed !!
Thank you for your positive comments. It means a great deal to me :-)
Brillant Video made the concept crystal clear. I was struggling with the structure of L Beta Galactopyranose as I was just remembering that if the OH is down then it is alpha. It worked until I met with L structures. Your point about the look at c6 and the anomeric carbon is Brilliant. This made it so much easier. I literally can't stress enough how mindblowing this video is Thank you man really thank you so much.
Hi Nate. Its been a while since i have looked at my youtube channel. What a lovely comment.Thank you so much. I might just start making more videos thanks to you. Regards, MG
I’m at last high school class in Poland. That topic was one of the most important for me and i always had trouble to learn it. After i watched this video i urserstood everything. Thanks a lot!!
Thank you! i'm a french student and it was exactly what i needed
Merci beaucoup. Je suis heureux que vous ayez trouvé ma vidéo utile. Salutations d'Australie!
I think this is the best video for understanding fisher's and hawarth's projection.
After reading many books and papers now finally I'm able to understand this topic because of this wonderful vdo...
Glad it was helpful! and thanks for your positive comments :-)
Thank you for teaching this! I’ve been having a hard time with this for daaays😅
Thanks Denise. How exactly did the video help you in your understanding? Just keen to know which segments of the video you found to be of most benefit. This will help me in how i create my future videos. Thank you :-)
Hi! It helped me understand how the structure was formed because you taught it step by step, and also how the different atoms interact with each other 😊
I can't describe your work qulification it is so legendly
Thank you!! That was such a kind gesture :-)
Holy smokes. This is one of the best, if not the best, video i've seen. It made me understand so well, and it answered all my questions. Thank you so much.
Thanks Sofia. What a lovely thing to say. It is much appreciated. Hope all is well on your side of the world. Regards, Wonders Of Chemistry :-)
THANK YOU! Nowhere in my textbook did it make sense like it did here.
No worries Jake. Thats great that video helped so much!! Feel frre to share with your fellow students :-)
Great work sir , I am from INDIA , so helpful video , i was struggling with this stuff . But you made it very simple and clear .
Thanks Rahul. I am glad that you found it useful :-)
This has been such an helpful video! I finally understood what substituents to look at when determining whether they are on the same side or the opposite side of the ring. One caveat I would have though, is alpha is on the SAME side, while beta sugar is on OPPOSITE side. I think the video might have reversed the two
You literally saved my life with this video, thank you so much !!! In this quarantine i am all by myself with my schoolstuff but this really helped me !! 👏🏻👏🏻👌🏼👍🏻🔥
Your welcome. Feel free to reach out if there is anything else that you think would be beneficial for a future presentation.
Thank you so much! I was looking at my class's powerpoint slides since I typically fall asleep in class and was mega confused. You saved my final exam I think/hope.
The presentation of the information was spectacular! The drawing and animation were some of the best I've seen on UA-cam. Will be definitely looking into your other videos, keep it up!
Wow, thank you!
Thank you so much, the video was short and on point, it really saved me a lot of time since I am preparing for uni-entrances
no worries, its great to hear that my video is assisting you with your preparation for entry into university based education. Good luck with it all. Regards, Wonders of Chemistry.
Give this man an award
Thanks Anuja. Your positive comments are much appreciated :-)
Thank you for your teaching. Way better than on class
Thanks Teresa. Do you have any other suggestions on what you believe you and your fellow students could benefit from within the realm of biochmistry that i have not already covered on my chanel? Maybe have a chat to your fellow students as well to see what they are struggling with? Regards, Wonders of Chemistry
Thankiess for this. I feel so confused when my teacher taught this in class. But with this video, I now understand the topic and I feel so proud with myself.
I've been struggling learning this concept ever since online class started. I'm so glad I was able to understand. 😭💕 Thank you so much
Thanks for the positive feedback. Comments like this motivate me to make more videos :-)
Happy to help!
THANK YOU SO MUCH! i have my orgo final today and my professor didn't really explain how to do this, so thank you for easing my stress about this topic :)
It is my pleasure. I hope you exam goes well.
Wondersofchemistry It went great! Thank you so much(⌒▽⌒)
Thats great news! Well done!!
Thanks a lot, now I understand much better after the clear explanation and examples!

SUPERB explanations!
It’s such an easy-to-understand presentation. Thank you
Thanks for the feedback. I am happy that you found the video useful. Feel free to share with your fellow students :-)
You the one that explain every detail thanks!
thank you so much for this video, this made me understand the concept more and also understand fully well how different fisher and haworth projections. You saved my grades! More power and Godbless!
Glad it was helpful!
Thank you so much sir,i am bangladeshi student, i was some confusion to this topics. Your delivered lacture helps me to understand.
Hi thank you for your kind words. I am glad the my video helped you understand this concept. Kind Regards, Wonders of Chemistry in Australia
Many many thanks for this session.
no worries
very good video with the practise at the end. made it much easier to ensure I got the hang of the concept.
Thanks :-)
this video is just perfect. God bless you, thank you so much for uploading on here such a clear explanation of this important part of biochem.
oh thank god bless you honestly.. i wasn't even studying chemistry this showed up in my biomolecules unit in bio and the alpha and beta glucose ring structures were bothering me so bad i had to make sense of it before i moved on... thank you!!!!!🙏
u truly have a way with clearing all potential doubts a student could have before they could even think to pause and ask LOL
So much easily explanation with 100% understanding
It was so perfectly explained...absolutely got it💓
Thank you :-)
Was a little scared about quality when there was a music at the beginning, but it turned out to be very helpful tutorial! thanks!
You're welcome!
You made this extremely easily to understand thank you 🙏
Thank you very much, I had a hard time with those exercices, but now I'm alright !
Great to hear :-)
this is great. turn right 90 degrees! who knew it was that easy? thank you!
You're welcome!
The only video that made me understand perfectly thank u
thank you. this was helpful beyond measure. more power to you.
Thanks for the positive comments :-)
Great.. thanks... I was confused in open chain chiaral No 5. here how OH becomes O and how vanished H. Now I'm clear. Because of rotation it happens nicely 🙂. Thank you, sir.
Amazing video! At around 6:00 however, the H+ does not attack, there is a proton transfer but the lone pair on the oxygen should attack the hydrogen in the end. Thank you so much! I have trouble with stereochem because it gets messy and I had trouble drawing structures in Haworth fashion but I have no trouble now!
thanks for your feedback :-)
lmao I said the same thing to myself. Awesome video though. Helped me understand. Do you have a video for Haworth to chair confirmations?
Thank you so much! Hope you help more students in the future bc u amazin!!!
thanks Leah
Great video! Surprised you don't have too many subscribers. You deserve a lot more!!
Thanks Antonio. Your channel looks pretty cool too. Regards, from Wonders of chemistry down under in Australia
I could not find the structer of l galactose...but now in this video help me a lot....thx...we want more video....
Thank you
Very clear concept. You made my life easy.
How do you know if the #5OH group is going to be pointing up or down to form the alpha or beta anomer from the Fischer projection? I can make the Haworth, but it seems to me every fischer projection in this video has been with the #5OH pointing down, so I don't know how to make anything other than the alpha anomer.
Hi Andrew, recall that objective of the OH functional group located on carbon number 5 of the fischer projection it to react and form an intramolecular bond with the aldehyde functional group located on carbon number 1. It is therefore non-existant after the formation of the cyclic structure and therefore has no bearing on whether the newly formed haworth structure is alpha or beta. What you should be focusing on is the relative positions of the CH2OH located on carbon 5 (cyclic structure) and newly formed OH on the anomeric carbon formed on carbon 1 (cyclic structure). If they are opposite sides of the ring (i.e., one facing up while the other is facing down) then you would be looking at the alpha anomer. On the other hand they are on the same side of the ring (both facing up or both facing down) then this would be the beta anomer. Feel free to contact me if you are still struggling with this. Regards, MG :-)
"I'll be RIGHT DOWN"
"Left it UP to me"
UA-cam should be the only school for learning quickly.
thumbs up :-)
Hey im from Poland. My english is so so. But this video is really good so I understand everything. Thank U ❤️
Dziękuję :-)
Thank you soooo much sir; this video is exactly what i was searching for.. it is so helpful : )
Thank you for your feedback. I am happy the video helped you :-)
Absolutely well explained.
Thanks so much for this video!! It was so helpful for biochemistry!!!
No worries. Thanks for the comments :-)
Thank you! Very clear and easy to understand
Glad it was helpful!
Great video, super clear. Thanks!
Thank a heap sir,,,,your presentation is so much excellent,,, i am from Bangladesh
Happy to help :-)
Hi tysm this was super helpful. I'm still a little confused in assigning priorities in order to distinguish between the L and D galactose. I don't see how the carbon 6 has a lower priority than the carbon 4 molecule. Would you please be able to elaborate on that. I hope this doesn't sound confusing lol
oh yes you should do a video on amino acids and peptide bond formation in addition to lipid formation!
Have a look at my playlist on lipids. ua-cam.com/play/PL5-8kYvBxU3pZEQnYtgAR8CfjF70KKKki.html You will see that i have included how lipids are formed. I will put peptide formation on my action check list :-)
Chemistry is even more interesting with these animation ❤❤
Very helpful for med school students thanks a lot !
Amazing explanation.
Glad you liked it!
This video is gold much thanks
Thanks Tyler :-)
Thanks a lot, the definition about alpha and beta helped me in dealing with questions based upon Haworth Projections of L carbohydrates
This was SO helpful-- thank you so much!!
Thanks Ragan!
you are a life saver, thanks a lot

This explains it so well thank you!!!!
Sir please we would be happy if you give a very detailed video on the formation of acetal and hemiacetal mechanism
acetal and hemiketal mechanism.
Thank you so much! This video is really helpful.
Excellent explanation 👍 thanks a lot
Super explanation sir I am from India....
Thank you for your positive comment. Regards, Wonders of Chemistry in Australia.
Thanks for the explanation
No worries!
explain it all without me even asking~~ thank you much i been wondering in my textbook why keep mentioned there is one more increasing * C after ring form and i been search which one lol now i see the whole meaning for this term and alpha beta clarification as well.
Happy to help!
Pneumonic to memorize placement "I'll be RIGHT down" put the function group down in Haworths projection.
"They Left it UP to me" put the function group up :)
Thanks a lot for this clear explanation!!
questions：1. Why do you stick to the right-down left-up rule? Can you explain geometrically? 2. Why can you rotate the three groups around the 5 carbon either clockwise or anti clockwise? Isn’t it supposed to be a strong bond in a ring? In reality, the three substituents are even in the same plane? How can you rotate? Wouldn’t it affect the other parts of the ring structure?
Wonderful explanation video thank you very much
Thanks for this video..the concept is crystal clear....👍👍👍👍
I am happy you found it to be useful
Best explanation ever😊😊😊
