Question

The amino group of each amino acid is comprised of: A) One nitrogen and two hydrogen. B) One carbonyl and one hydroxyl. C) One carbonyl and two hydronyls. D) None of the above.

Answer 1

The amino group of each amino acid consists of one nitrogen and two hydrogen atoms, corresponding to option (A).

Step-by-step explanation:

The amino group of each amino acid is comprised of one nitrogen and two hydrogen atoms, which corresponds to option (A). This group is represented chemically as
`-NH₂` no acids serve as the monomers that make up proteins. Each amino acid consists of a fundamental structure that includes a central alpha (α) carbon, to which the amino group (
`-NH₂` carboxyl group (
`-COOH`d a hydrogen atom are all covalently bonded. The R group, which is also bonded to the alpha carbon, is distinct for each amino acid and imparts unique chemical properties to each one.
