Identification of PTH-Amino Acids by HPLC SpringerLink
WebSince the phenylthiohydantoin includes the R group of the N terminal amino acid, identification of the phenylthiohydantoin also identifies the N terminal amino acid. The other product of the Edman degradation is also a peptide -- it is the original peptide minus the original N terminal amino acid. WebPhenylthiohydantoin (PTH) Definition Phenylthiohydantoin is an organic molecule, which is formed when protein is degraded by Edman degradation method. As the name explains, it … buy gold mobile number
