Identify the amino acid represented in the diagram below.

Step-by-step solution

Amino acids are substituted methanes as these consist of four bonds. These are carboxyl group, amino group, hydrogen and variable R group. Since the carbon in amino acids have four different bonds, it is considered as chiral carbon and such amino acids are optically active, amino acids are mostly laevorotatory. The given structure has the variable/functional R group H and hence it is glycine amino acid.
