Levorotatory amino acid

Vedclass · Answer

(B) The $L-$ and $D-$ designations for amino acids refer to the configuration of the molecule relative to glyceraldehyde,not its optical rotation. $L-$amino acids are those where the amino group is on the left side in a Fischer projection. While $L-$amino acids are often levorotatory,this is not a universal rule,as some $L-$amino acids can be dextrorotatory. However,in the context of standard biochemistry multiple-choice questions,$L-$amino acids are frequently associated with the levorotatory property,though the term refers to the spatial configuration (stereochemistry) rather than the direction of light rotation.
