Products for Amino Acid Hydrolysis

Hydrolysis is typically achieved by acid conditions. A standard procedure is hydrolysis with 6 M hydrochloric acid (24 hours, 110°C). These standard procedure is a compromise between time requirement and temperature. Sensitive amino acids (especially tryptophan and cysteine) will be partially destroyed. Gas phase hydrolysis and addition of other acids (e.g. propionic acid, TFA, methanesulfonic acid) can be used to shorten the hydrolysis time and improve the yield of sensitive amino acids.
