This side is the carboxyl side. So the right side is the carboxyl side, and this is that carboxyl peptide bond, while the other side is the amino side. And this is that amino peptide bond. And what Chamotrypsin does is it only cleaves, methionine, phenylalanine, tyrosine and tryptophan on the carboxyl side on the right side of that amino acid. So if we examine, let's say, methionine, so this is our side chain group of methionine. This is the green bond that will be cleaved by the climate cryptIn.
