In minute 17:00 shouldn't there be 9 chiral centers and not just 8. I am referring to the carbon under the second carbon that you numbered. Isn't that also a chiral center since it is attached to 4 different groups?
@@Curiousviewer23 I thought the same too but I just goggled for the structure of cholesterol and he has the wrong structure....the particular c you speak of own the double bond too that was put away
My man has guided me through my general chemistry classes, my general physics classes, and now he's coming through for my organic chemistry classes. At this point I'd trust this man with my entire life xD
Your videos helped me study throughout my bachelor's degree in chemistry . I am currently a Pharmaceutical Technology grad student and i also work part time as an chemistry tutor and i still watch your videos in order to prepare my lesson plans. I have no words to express my gratitude for your help through all these years!
TY, I appreciate all your hard work. I watch many of your videos and they have helped a lot! ***Possible CORRECTION? looks like the cholesterol molecule in your video has the double bond in the wrong place. *** I kept going over and over this and could not understand why Carbon-5 (the one due south of the methyl group) was not a chiral center? As the figure is drawn, it should be...which would make 9 stereocenters, not 8. But when I looked up cholesterol, the double bond is actually between C-5 and C-6 not as you've shown it. Just in case anyone else got stuck on this problem.
Thanks for this comment. I've been sitting here the past few minutes trying to figure out why there would only be 8 given the drawing in the video. After looking up what cholesterol should look like, it makes sense.
the double bond in the cholesterol is incorrect. it needs to be moved one bond to the left. I kept thinking there were 9 chiral centers until I googled it. Keep up the great work!!
i don't even know where to start but i hope your pillow is cold at night, i hope you eat everything you crave, and i hope you'll only get all the happiness in life. thank your for saving me.
Despite the fact that I'm watching this video after two years of release, it still serves it's suppose. That's a rare feature of an outstanding teacher. Thank you❤❤❤
Would definitely like to see the face behind the man behind my success. The organic chemistry tutor has helped me Ideally with statistics, Calculus, a bit of genetics, general chemistry, Physics and organic chemistry ❤️
He made a small error and drew the double bond in the wrong place. So, you're right that the molecule shown has 9 stereocenters! In reality, cholesterol only has 8. You can confirm this by googling the molecule. xx
I'm from Pakistan, student in Germany. You have taught me what my professor was not able to do from a whole month. May God bless you! Keep up the good work.❤
All the way from Kenya, taking bachelor in education chemistry and physics, this man has walked me from my first year of course to current 4th year. keep up. I wish you All the best and live long mahn.
Another incredible video; thanks so much for posting! If the hydrogen (or lowest priority group) isn't where I want it to be, sometimes I just exchange two groups to make that happen, and remember that that inverts the stereochemistry (R -> S or vice versa).
I really appreciate your videos. You have helped me throughout my stereochemistry course. I'm currently studying bachelor degree in pharmacy and you have guided me throughout the entire course. You are the best.❤🙏
Thank you so much. I'm literally sitting here learning what my professor couldn't teach for 2 full lessons. Meanwhile, my sis is also watching one of your vids in another room to teach herself physics since her teacher isn't great either 🤣 keep up the good work educational vids!
Found this and I just had to like and Subscribe. I am in my 2nd year studying BSC in Public Health Nutrition and this course has been challenging for me, but your explanations have made my life easy. I will be handing in my assignment on Monday 15/08/22 and I am hoping to ace it. ❤️
At first I thought that you missed a chiral center (the tertiary carbon directly underneath chiral #2) but I looked it up and the double bond you drew was just in the wrong place! That carbon is supposed to be sp2 hybridized, just FYI for anybody else confused.
I know you probably wont read this, but I want you to know that my Organic Chemistry professor didnt even mention you could just skip over four. She overcomplicated it by making you switch configurations twice, etc...thank you so much.
thanks, sir.. i really appreciate your video.. i've been watching your vid ever since my 1st sem.. thankfully, previous semester i got an A for my chm.. wishing u a best in health
Holy clutch, amazing how you pay thousands to take a class and all they say is read the book and my office hours are from 8-9am every friday. Luckily we have you, cheers man.
The position of the C=C in cholesterol is wrong, according to your drawn diagram, there should be 9 chiral centers, but for cholesterol, there is only 8 because of the positioning of the C=C. But other than that, I loved the video and it helped me a lot in understanding stereochemistry.
For Q3, the one assigning chiral centers for Cholesterol, would there not be a chiral carbon just below the 2nd chiral carbon? It is attached to a sp2 hybridized carbon, the carbon with a methyl group, and a ch2 carbon that eventually leads to an alcohol
Yes, he drew the double bond incorrectly, the two cicle hexanes are supposed to be "fused" via a double bond between the carbon under chiral carbon 2 and the carbon to it's right, so in the cholesterol molecule there are only 8 chiral centers, but the molecule shown in the video has 9 chiral centers.
When identifying the chiral centers on cholesterol, I think you accidently missed one and it would be 9 instead of 8. Isn't there a chiral center on the carbon below the one you indentified as 2?
You are right! Based off of his structure, there are 9 chiral centers. However, the double bond in his cholesterol drawing is in the incorrect position; it should be moved one spot to the left. After that change, there will only be 8 chiral centers
Dude thank you so much seriously u helped me through chemistry a lot like u don’t know how much u helped me The way ur so relaxed while explaining makes me feel so reassured ahh thank u thank u so much
Thanks man, for helping me finally understand this. I'm a pharmacy student and the notes the teacher gave me was just full of bullshit and couldn't understand shit. You've helped me out here. Hope you make more videos like this and help others like me.

I've got a question regarding the Hydrogen Atoms in the Cholesterol Molecule. Did you follow any rules when placing the Hydrogens in between the Carbon structure regarding their position behind or in front of the planes? Or is their position arbitrary? Thank you so much for this great tutorial. It really helps!
In problem 3, why is the tertiary carbon closest to the double bond not considered a chiral center? I am talking about the bottom right carbon on the farthest benzene to the left of the cholesterol.

17:08, isn't there another chiral center below carbon #2, since first bond goes to a sp3 C, second to sp3 CH2, and third to a sp2 CH and a hydrogen?
yess there are 9 not 8 chiral Cs
Brilliant you are correct.. Wanted to ask too
Yes, he drew the molecule with the double bond in the wrong place. Cholesterol has 2^8 isomers but the drawn molecule has 2^9.

17:07 Shouldn't the tertiary carbon beneath the one numbered 2 be counted as a chiral center?
