Question

How is chirality related to amino acids?

Answer 1

All amino acids, except glycine, have chiral centres and can form enantiomers - optical isomers.

Explanation:

Optical isomers have different biological properties, so one enantiomer can have a distinct taste while the other enantiomer can have the opposite taste.

Also, enantiomers may not fit into the same enzyme. This can cause medical problems if the wrong enantiomer is present.
