Aspartame is an artificial non- saccharide sweetener 200 times sweeter than sucrose and is commonly used as a sugar substitute in foods and beverages. [ 4 ] It is a methyl ester of the aspartic acid / phenylalanine dipeptide with brand names NutraSweet, Equal, and Canderel. [ 4 ]
Other colors used are green for stevia. [1] A sugar substitute is a food additive that provides a sweetness like that of sugar while containing significantly less food energy than sugar-based sweeteners, making it a zero-calorie (non-nutritive) [2] or low-calorie sweetener. Artificial sweeteners may be derived through manufacturing of plant ...
Aspartate transaminase (AST) or aspartate aminotransferase, also known as AspAT/ASAT/AAT or (serum) glutamic oxaloacetic transaminase (GOT, SGOT), is a pyridoxal phosphate (PLP)-dependent transaminase enzyme (EC 2.6.1.1) that was first described by Arthur Karmen and colleagues in 1954. [1][2][3] AST catalyzes the reversible transfer of an α ...
The artificial sweetener aspartame has been the subject of several controversies since its initial approval by the U.S. Food and Drug Administration (FDA) in 1974. The FDA approval of aspartame was highly contested, beginning with suspicions of its involvement in brain cancer, [1] alleging that the quality of the initial research supporting its safety was inadequate and flawed, and that ...
Infobox references. Aspartic acid (symbol Asp or D; [4] the ionic form is known as aspartate), is an α- amino acid that is used in the biosynthesis of proteins. [5] The L -isomer of aspartic acid is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. D-aspartic acid is one of two D -amino acids commonly found in ...
A common sweetener, aspartame is to be labelled a possible carcinogen next month
Accordingly, all products in Australia, the U.S. and Canada that contain aspartame must be labeled: "Phenylketonurics: Contains phenylalanine." In the UK, foods containing aspartame must carry ingredient panels that refer to the presence of "aspartame or E951" [16] and they must be labeled with a warning "Contains a source of phenylalanine." In ...
Dipeptide. A dipeptide is an organic compound derived from two amino acids. The constituent amino acids can be the same or different. When different, two isomers of the dipeptide are possible, depending on the sequence. Several dipeptides are physiologically important, and some are both physiologically and commercially significant.
