Identify the basic amino acid from the following.

Step-by-step solution

Amino acids based on a number of NH 2 and COOH groups can be classified into three types: Neutral amino acids: The amino acids having an equal number of amino and carboxyl groups are called neutral amino acids. E.g. Glycine, alanine, valine, leucine, isoleucine, proline, methionine, tryptophan, phenylalanine, serine, threonine, cysteine, asparagine, glutamine, and tyrosine. Acidic amino acids: The amino acids having more carboxyl groups as compared to amine groups are called acidic or negative amino acids. E.g. Asp
