Aspartame [Nutrasweet, Equal (Searle Consumer Products, Chicago, Ill.)] is the methyl ester of the dipeptide aspartylphenylalanine (Asp-Phe). After hydrolysis of the ester bond in the intestinal lumen, the dipeptide is apparently absorbed and digested in the same manner as dipeptides

A new beta-aspartyl dipeptide, N-beta-L-aspartyl-L-phenylalanine (beta-AP), has been isolated and identified in urine and plasma from normal human volunteers. beta-AP was isolated from urine samples by high performance liquid chromatography (HPLC). Its identity and stereochemistry were demonstrated by HPLC and

As part of the series investigating the structural features of C-terminal amidated amino acids and peptides, three crystal structures of Z-Gly-Phe-NH2, Tyr-Lys-NH2, and Asp-Phe-NH2 were analyzed by the X-ray diffraction method, and their molecular conformations and intermolecular interactions were investigated.

Aspartame (L-aspartyl-L-phenylalanine methyl ester, is a widely used artificIal sweetener. In humans and other animals aspartame is initially hydrolyzed to L-aspartyl-L-phenylalanine by intestinal esterases. L-Aspartyl-L-phenylalanine inhibits angiotensin converting enzyme purified from rabbit lungs with a Ki of 11 +/- 2
