<P> Proteins are polymer chains made of amino acids linked together by peptide bonds . During human digestion , proteins are broken down in the stomach to smaller polypeptide chains via hydrochloric acid and protease actions . This is crucial for the absorption of the essential amino acids that can not be biosynthesized by the body . </P>
