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

Some solid-state pharmaceutical properties and the solid-state thermal stability of the model dipeptides aspartame (APM) and aspartylphenylalanine (AP), have been investigated. Studies by differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), high-performance liquid chromatography, powder X-ray diffraction, and optical microscopy

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

Nutrients, 12(6) (2020-07-01)
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
