Concept explainers
(a)
Interpretation:
The chirality of amino acids should be identified.
Concept introduction:
Chiral: Absence of a plane of symmetry or a center of symmetry is called chiral molecule, a non-superimposable on its mirror image is called chiral. A carbon atom is attached by the four different groups is called chiral carbon.
Achiral: Presence of a plane of symmetry or a center of symmetry is called achiral molecule, a superimposable on its mirror image is called achiral. A carbon atom does not have four different groups is called achiral carbon
(b)
