Can you predict the absolute configuration ( R or S ) of an amino acid from its D or L designations?

Could someone explain this to me? Thank you

Answer #1

Solution :-

The D and L notations used to indicate the rotation of the plane polarized light by the molecule but the R and S are the absolute configurations of the specific chiral centers therefore if the molecule have more than 1 chiral centers then it can have different absolute configurations (R and s) for the different chiral centers but the overall rotation of the plane polarized light is different so we cannot predict the R and S configurations from the D or L designations.

Biochemists who study protein structure and function often introduce mutations (changes) to a protein's amino acid sequence. One common change is an amino acid substitution that can creates a modified protein that can mimic (function similar to) a phosphorylated protein. Using what you know about different amino acids, which amino acid(s) would be a good choice for this change to a phosphorylated-like state? Briefly explain why.
