Detailed explanation-1: -Amino acids are natural compounds composed of amine (–NH2) and carboxylic acid (–COOH) functional groups, linked to the same carbon atom.
Detailed explanation-2: -An amino acid contains both an amino group, -NH2, and a carboxylic acid group, -COOH, in the same molecule.
Detailed explanation-3: -An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid.
Detailed explanation-4: -These molecules are called amino acids because they all share two functional groups in common: an amine group (-NH2) and a carboxylic acid group (-COOH). With the exception of proline, they all have the same backbone: NH2-CH-COOH.
Detailed explanation-5: -Amino acids are bifunctional organic compounds, hence it contains both carboxylic group (−COOH) as well as amino group (−NH2)
