Question

In amino acid monomers, the side group (R) is covalently bound to:

a. The alpha-carbon.
b. The carboxyl carbon.
c. The amino nitrogen.
d. The hydroxyl oxygen.

Answer 1

a. The alpha-carbon

Step-by-step explanation:

An amino acid is an organic molecule that contains a carboxyl (COOH) and a amino (NH2) group. It has a central carbon called as alpha carbon.

The carboxyl and amino groups are attached to the the alpha carbon. Apart from them, a side chain denoted by "R" is also covalently attached to it. Side chain varies in each amino acid and it imparts the unique properties to the particular amino acid.
