Vedclass · Answer

(B) In biochemistry,the prefixes $D-$ and $L-$ are used to denote the stereochemical configuration of molecules,specifically referring to the spatial arrangement of atoms around a chiral center.These designations are based on the configuration of glyceraldehyde,which is the simplest sugar.$L-$ indicates that the molecule has a configuration related to $L$-glyceraldehyde,where the functional group (such as the amino group in amino acids) is on the left side in a Fischer projection.It is important to note that $L-$ does not necessarily mean the molecule is levo-rotatory (which refers to the rotation of plane-polarized light); rather,it describes the relative configuration.

What does $L$ indicate in $L$-lysine and $L$-malic acid?
