Type of amino acids obtained by hydrolysis of proteins is :

Step-by-step solution

Proteins are natural polymers composed of α -amino acids which are connected by peptide linkages. The smallest unit to which the protein can be broken down is called amino acids. The α -amino acids are the amino acids whose one carbon contains both the amino group NH 2 and the carboxyl group COOH . This type of carbon is called α -carbon. Thus, the amino acid that contains an α -carbon is called an α -amino acid. Proteins upon acidic hydrolysis produce α -amino acids. Hence, the answer is option B.
