Aspartame. Molecular model of the artificial sweetener aspartame. Atoms,represented as spheres,are colour-coded; carbon (blue),hydrogen (white),oxygen (red) and nitrogen (dark blue). Its chemical name is L-alpha-aspartyl-L- phenylalanine methyl ester. Aspartame is about 180 times sweeter than sugar. It has no energy value and is therefore used as a sugar substitute in diet food,drinks and sweeteners. It contains the amino acid phenylalanine and must carry a warning on the product packaging. This is because people who suffer from the condition phenylketonuria cannot metabolise phenylalanine,and over- consumption can lead to mental retardation | |
