Common_Name | L-Aspartyl-L-phenylalanine |
Description | This is a metabolic byproduct of aspartame (Nutrasweet). Aspartame is the methyl ester of aspartylphenylalanine. After hydrolysis of the ester bond in the intestinal lumen, the dipeptide is apparently absorbed and digested in the same manner as dipeptides derived from protein digestion. There are several Asp-Phe dipeptidases that degrade this peptide. It has been suggested that individuals with aspartame allergies may be defficient in this peptidase. (PMID 3743970). It has been observed that the N-beta-L-aspartyl-L-phenylalanine (a breakdown product of Asn-Phe) is a naturally occurring peptide found in both blood and urine.(PMID: 2723819) |
