The dipeptide sweetener aspartame (N-L-alpha-aspartyl-L-phenylalanine, 1-methyl ester; alpha-APM) is relatively stable in dry powder form. However, when exposed to elevated temperature, extremes of pH and/or moisture, alpha-APM is converted into a variety of products. In aqueous solution alpha-APM decomposes to

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.

Phenylketonuria and tyrosinemia type 1 are treated with dietary phenylalanine (Phe) restriction. Aspartame is a Phe-containing synthetic sweetener used in many products, including many 'regular' soft drinks. Its amount is (often) not declared; therefore, patients are advised not to consume

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
