@@andrewjustin256Sometimes you learn something in high school that you will also learn in university but in more depth. Therefore, the answer to your question is yes, we do learn this in college but the material is way more detailed. It also depends on your major, for example, as a chemical engineering major I don’t need to know as much as a biology student.
I have had many lectures in biochem concerning this topic. I leaned more in this 13 minute video than many hours of lecture. The hand-drawn molecules are really well done too. Thank you for your generosity.
At first glance the study of human anatomy seems to bo extremely complicated. It's true that it's not simple and your studies wont change that. As for it being overwhelming, that can be eleviated if you take your study one step at a time. I found an article on Sebs Study Crammer very helpful for this.
I signed in just to tell you how awesome you are and how much of a help these videos are. Keep up the good work and know that everyone here appreciates your efforts.
This was the most efficient video I have ever seen, everyone taking biochemistry needs to know about your channel. Thank you. I will try to spread the word.
When you read this so many times from your college book and still facing troubles with fully understanding the topic, So you head to here and finally realize how simple that was, here's hits dopamine
Your videos are absolutely incredible! It's amazing that you're able to take the most relevant and important topics of each subject so that we're better equipped with understanding lecture, no matter who the lecturer/how the class is taught
I literally sat for hours and for like about 4 sessions with many people trying to understand the session about haemoglobin. If only I saw this vdeo before!! Awesome job mate keep it up. We, strudents of University of Kufa, College of Medicine watch your videos whenever there is one concerning a topic we're studying.
This guy is the real MVP. What a gem! You sir are very skilled at your craft. You make complicated concepts seems so simple. What a great explanation. Thank you!
Sitting in my biochem class watching this video and looked up in front of me another student is watching AKL as well. We both will do great on this part.
Thanks million times, you are amazing. I have been watching your videos for different topics. very precise, clear, simple and beneficial. Thanks again.
You're saving my ass in biochem! You break these topics down into their fundamental aspects and make it so easy to understand. Way more effective than reading from a book cluttered with horrible examples and round about language. Keep it up! I'll be tuning in for MCAT prep for sure.
Andrey, you've truly got a talent for teaching. I've used your content for many classes, including biophysics, optics, biochemistry, etc. You have always immediately and substantially improved my understanding of the content. I couldn't do this without your help. You're much appreciated. Best wishes.
The iron atom at the centre does not have a +6 charge. It has a +2 charge to begin with. The reason why the iron atom makes bonds with the nitrogens and oxygen is that it is a transition element and forms 6 hybrid orbitals (empty) around itself ( complex formation in transition element ). So now 4 nitrogens from the protoporphyrin. 1 nitrogen from histidine and 1 oxygen molecule make coordinate covalent bonds with the Fe2+. I don't also agree with the reasoning that iron moves because oxygen is more electronegative. Oxygen makes a coordinate covalent bond with iron. (It gives electrons). It would really be helpful if you could clarify this.
Thanks for the video! Do you mind explaining how the formal charges were assigned for the iron-oxygen complex? For example, why wouldn't the O attaching to Fe ion have a charge of +1 (a double bond, a single bond and a lone pair)?
Sir your lectures are very explanatory and ssly u cleared my doubts which I found after reading notes. I could understand it by creating good imaginations. So thank you so much sir.
Super helpful! Thanks for making the videos. Only request (take it or leave it) is that if your videos are in series, could you number them? I stumbled upon one in my desperate google search and would have loved to have realized there was a whole series, because these are GOLD (either stand alone or in a series I might add). Either way, thanks for making the videos and keep it up. I've already shared them with some of my classmates!
Sir,may i know how can we predict the octahedral geometry of fe+2 in high spin in deoxy,bcoz there r only 4 electrons available in t2g and eg orbital of iron.and there are no vacant orbitals available for dative bonding in fe?
Has an oxidation state of 2+ because it contains only 6 electrons out of the 8 valence, not because it can have 6 bonds but only has 4. if that were the case, than the oxygenated heme in hemoglobin, the iron atom contained would have an oxidation state of 0 which is experimentally untrue (it has oxidation state of 3) this is because it undergoes a redox reaction with molecular oxygen forming the superoxide ion and the Iron 3+ ion.
As a college student who watched this litterally 4 hours before exam, I salute you
Im like 1 hour and 15 minutes before exam

😂😂😂😂 that’s me
Do you guys learn these types of topics in college? I mean, I am in ninth grade and I am learning this.

And this my friends, is how you summarize a 3 hour biochem lecture into 13 minutes. You're a life saver!
You guys are the sole reason I understand what is going on in Biochemistry. Thank you so much for your time and effort.
This was the most efficient video I have ever seen, everyone taking biochemistry needs to know about your channel. Thank you. I will try to spread the word.
+Random Gryffindor Thanks!! :)
the amount of sense you make in your videos makes me addicted to them , keep up the amazing work
thanks so much for all of your hemoglobin videos. made a ton of sense and much easier to understand than my textbook! you are great!
"and what that means is..."
thank you.
This is the best video ive ever watched in my college career. Amazing teaching style. So clear and intuative
Thank you so much! I am currently taking Biochemistry in college and finding it hard to understand. You explain it so simply!
+Zoe Harper Thank you Zoe! Im glad you're finding my lectures helpful! Spread the word :-) and keep me posted on your progress!
you're an awesome teacher! Wish you had more videos related to biochemistry for medical and dental students! Keep up the good work!
I can’t found one can explain like you!
You’re wonderful and versed in explaining different topics.
When you read this so many times from your college book and still facing troubles with fully understanding the topic, So you head to here and finally realize how simple that was, here's hits dopamine

Wow. it's my first time having a crush on an organic molecule. It works magically. Thank you for your magical explanation as well.
Best video on hemoglobin. Hands down.
Really appreciate every minutes in this video. I was soo last, but with video I made sense everything. I truly thank you.
im speechless........this is so easy to understand
Thank you so much I'm struggling w biochem and the neither the books nor my professors explained the topic this well. Thank you so much for the help!
i love this it was hard but with you explanation was easy to understand THANK YOU
Excellent, excellent, exellent. no other words. thank you, you will be in my prayers.

Hey Ak, I find your lectures easy to comprehend and I use your definitions for flashcards. I was wondering, can we get a copy of your lecture notes?
thank you sir!
Very well explained
thank you so much
Thanks to make it simple 💙
You're amazing..... Amazing amazing... Amazing
Do you have those notes from the board on a pdf or somewhere where we could print them out? Thanks for clarifying biochem for me; you're amazing!
Amazing Sir
Thanks!
i have a question: where do you find the distal histidine? from the same Protein where the proximal histidine come from?
THANKS
Why is it specifically Histidine which binds to the Fe2+? Could it be some other amino acid?
keep up the good work. fantastic to learn with you.
greetings from germany!
proxiii1234 Thanks! glad i have an audience all the way in Germany :)
I got more out of this video in 13 minutes than what I did in two, two hour lectures
Sir,may i know how can we predict the octahedral geometry of fe+2 in high spin in deoxy,bcoz there r only 4 electrons available in t2g and eg orbital of iron.and there are no vacant orbitals available for dative bonding in fe?
Very nice explanation
this helped a lot! What about when carbon monoxide binds? Could you make a video on this?
*What is the importance of the methyl, vinyl and propionic acid to the hemoglobin structure*
THE BEST BIOCHEMISTRY VIDEOS EVVEEEERRRRRRRR
A great lecture... but where does the distal histidine come from?
many thanks for your amazing efforts
Suheel Sorani you're welcome :) thanks for watching!
many thanks for your brilliant presentations

Question: if Bilirubin is a degredation product of hemoglobin, where does it play a role in this molecule? Thank you.
Buraya Türkçe yorum yazan ilk kişi olmak istiyorum. Onca ders dinledim ama bu adam gibisini dinlemedim. Daşşaklarına kurban senin :D
sir, but doesn't the +2 charge become +1 when the Fe bonds with the histidine?
