The function of the digestive system is to break down these large molecules (called polypeptides) into smaller molecules (called amino acids). Pepsin in your stomach is an enzyme that chemically breaks down (hydrolyses) many protein molecules into less complex, smaller chains of amino acids.The stomach does not break down all proteins completely into amino acids.The digestion of protein is completed by the enzymes in the small intestine by another enzyme called trypsin. The relatively small molecules of amino acids enter the bloodstream in the small intestine.he stomach does not break down all proteins completely into amino acids.
