Question

look at the molecule shown below. which statement about the r - side chain of this molecule is correct? amino acids amino group side chain carboxyl group r - ch(nh2)cooh this region is involved in formation of the peptide bond. this region is the amino group of the amino acid. this region is the carboxyl group of the amino acid. this region is the same in all amino acids. this region determines how the amino acid interacts with other molecules.

Explanation:

The R - side chain of an amino acid is unique to each amino acid and determines its chemical properties and how it interacts with other molecules. The amino and carboxyl groups are common to all amino acids and are involved in peptide - bond formation.

Answer:

This region determines how the amino acid interacts with other molecules.
