Acid Casein Peptone is an acid hydrolysate of casein. The agent in a complete or total acid hydrolysis is commonly hydrochloric acid (6-8 N). Acid hydrolysis is a crude process that cleaves all peptide bonds. Acid hydrolysis commonly results in a total hydrolysis of protein to amino acids. The process destroys glutamine, asparagine, tryptophan, cysteine, serine, threonine, lysine, aspartic acid, proline, racemizes amino acids and completely destroys vitamins.
