... - Most amino acids (except glycine) have four different groups attached to the a-carbon and therefore are chiral or have a chiral center. - For glycine, R is hydrogen. Therefore, the mirror images ARE superimposable and NOT chiral. A plane of symmetry exists. - Each amino acid except glycine has 2 E ...
