Question

The chemical and physical properties of amino acids is based upon
A. Amino group
B. Carboxyl group
C. R group
D. All of these
____Explain with Reason_____​

Answer 1

Answer:

carboxylic group

Explanation:

Each amino acid contains a central C atom, an amino group (NH2), a carboxyl group (COOH), and a specific R group.

The R group determines the characteristics (size, polarity, and pH) for each type of amino acid.

Peptide bonds form between the carboxyl group of one amino acid and the amino group of another through dehydration synthesis.

A chain of amino acids is a polypeptide.
