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
