Find the structure of a tetrapeptide using the clues presented below. Draw the chemical formula of the peptide. * Full hydrolysis of the peptide yields equimolar amounts of alanine, aspartic acid, glycine, serine and ammonia. Sanger analysis of the peptide yields 2,4- dinitrophenylalanine. (formula, equation?) Carboxypeptidase enzyme doesn't hydrolyze the peptide. (Why?) * Partial hydrolysis of the peptide yields the following fragments, each with unknown order: Ser, Ala, Gly Gly, Asp NH3
