This video will give you an in-depth review of everything you need to know about Amino Acid stereochemistry. We’ll start with a review of how to find R and S for simple and complex molecules, including what to do when substituents start with the same atom.
Practice finding R and S for a few amino acids,
Then we’ll continue with Fischer projections including how to read, draw and find both R and S as well as D and L.
We’ll compare R&S to D&L and learn how to quickly convert between Fischer and 3D
And we’ll end with a few more practice examples of amino acid stereochemistry

I want to cries everytime I study for the MCAT. I swear I can feel physical pain looking at these 😢

[@Leah4sciMCAT]

I'm so sorry to hear that! Have you checked out the resources on leah4sci.com/mcat? I want to help you reach your MCAT goal

[@tomokochii]

Wow❤❤❤ im from chile i'm studying nursing i've always accomplished with chemistry, but you saved meee 😭😭😭😭 thank you very much!!!!!

[@Leah4sciMCAT]

I am so happy to help! Nurses are SO needed worldwide, keep going!

[@officialkevinle]

Great video, thank you. Would you recommend watching the longer video on the same topic as well?

[@Leah4sciMCAT]

That's up to you, the longer video goes into more depth with more information, but the takeaway should be the same

[@abenaboateng650]

Great video, thanks!

[@Leah4sciMCAT]

You're very welcome!

[@joevenskyseme7760]

Hey Leah! Just to clarify, when you mentioned 'except for cysteine,' does that imply that for cysteine, the stereochemistry is reversed, meaning D corresponds to L and R corresponds to S?

[@stanley5830]

love your videos Leah!

[@Leah4sciMCAT]

Thank you, glad you like them!

[@matrutirthamishra8208]

Thank you so much mam
