WebTrypsin, chymotrypsin, and elastase are collectively called protein scissors. They cleave the protein bonds and release the amino acids. Each one of these enzymes cut the proteins at specific places of amino acid. Namely the trypsin cleaves at the end of lysine and arginine. Chymotrypsin cuts near the large amino acids and phenylalanine. WebTrypsin and chymotrypsin have similar tertiary structures, although very different substrate specificities. Trypsin hydrolyzes peptides at Lys/Arg residues while chymotrypsin … WebpH will affect trypsin action. as pH increases, tryrpsin will show increasing activity up to an optimum pH. the action of the enzyme trypsin on the substrate egg albumen will be at a maximum at an optimum pH of around 7 (neutral) to 8 (slightly alkaline) see later about pH of duodenum. as pH continues above this, trypsin activity will decrease. electric chainsaw lidl offer
