BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases. From your stomach, these smaller chains of amino acids move into your small intestine.

Detailed explanation-2: -Enzymes in the stomach and small intestine break down proteins into amino acids.

Detailed explanation-3: -Protein foods are broken down into parts called amino acids during digestion. The human body needs a number of amino acids in large enough amounts to maintain good health. Amino acids are found in animal sources such as meats, milk, fish, and eggs.
