BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Complete answer: Proteins are digested into small peptides and amino acids in the small intestine before they get absorbed.

Detailed explanation-2: -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-3: -Food Sources 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.

Detailed explanation-4: -When you eat food the body’s digestive system breaks down the protein into the individual amino acids, which are absorbed and used by cells to build other proteins and a few other macromolecules, such as DNA.

Detailed explanation-5: -Enzymes in the stomach and small intestine break down proteins into amino acids.
