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: -Chemical digestion For example, proteins are broken down into their ‘building block’ amino acids. Once released, these small molecules can then be absorbed through the gut wall and into the bloodstream.

Detailed explanation-3: -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-4: -During digestion, proteins are broken down into amino acids through hydrolysis. The amino acids dissolve in our blood and are carried to tissues and organs. There, the amino acids are either used as a source of energy or are assembled into proteins through condensation polymerization.

Detailed explanation-5: -Our bodies use special protein molecules called enzymes to break the larger molecules into smaller pieces. Enzymes are catalysts. Each enzyme is very specific and only attaches to one type of molecule. The molecule the enzyme acts upon is called its substrate.
