WebbKeratin is completely insoluble in cold or hot water; it is not attacked by proteolytic enzymes (i.e., enzymes that break apart, or lyse, protein molecules), and therefore cannot replace proteins in the diet. The great stability of keratin results from the numerous disulfide bonds of cystine. WebbThe simplest level of protein structure, primary structure, is simply the sequence of amino acids in a polypeptide chain. For example, the hormone insulin has two polypeptide chains, A and B, shown in diagram below.
WebbThe primary structure of a protein refers to the specific amino acid sequence of the protein, plus the peptide bonds that join each of these amino acids together. In other words, the primary structure of a protein …
