<prompt> The enzyme trypsin is specific for peptide bonds of:Basic amino acidsAcidic amino acidsAromatic amino acidsNext to small amino acid residues  <response>: Ans. A. Basic amino acidsTrypsin is an endopeptidase which cleave protein chains at internal peptidebonds, but each preferentially hydrolyses bonds adjacent to a particular type of amino acid residue. Trypsin cuts just next to basic residues lysine or arginine; chymotrypsin cuts next to aromatic residues phenylalanine, tyrosine or tryptophan.
