Outline the process of protein digestion from the mouth through the large intestine


?In the mouth, proteins are softened and mixed with saliva. In the stomach, the hydrochloric acid denatures the proteins into highly accessible polypeptide chains, which can then be cleaved into smaller polypeptides with the enzyme pepsin. In the small intestines, the smaller polypeptide chains are further broken down with peptidases into individual amino acids, which can then be absorbed. Amino acids rarely end up in the large intestine, but are introduced into the blood stream and removed later by the liver for excretion as urine.
