WebThe hydrolysis of a peptide bond is helped along by two common means, and those two means are with the help of strong acids or with proteolytic enzymes. So when we use strong acids, we call this acid hydrolysis. And acid hydrolysis, when combined with heat, is a nonspecific way of cleaving peptide bonds. Webhydrolysis: [noun] a chemical process of decomposition involving the splitting of a bond and the addition of the hydrogen cation and the hydroxide anion of water.
