How the artificial sweeteners are available as sugar substitute?

Some of these are available as tablets, as sugar substitute and others appear as ingredients in many food products, not just in 'diet' foods. Out of the compounds shown, aspartame finds maximum use in the food and other products.

The chemical name for aspartame is N-L-α-aspartyl-L-phenylalanine 1-methyl ester, thus the name aspartame was extracted. In 1965, James Schlatter, of the G. D. Searle pharmaceutical company, inadvertently tasted an experimental compound that he had synthesized in an attempt to discover a better gastric hormone inhibitor, an ulcer drug. This unexpected and fortunate event (for, as we all know, we are instructed to limit exposure to chemicals with unknown properties) led to the development, approval, marketing, and acceptance of the most widely used "artificial" sweetener in the world called ‘aspartame' more commonly known by its trademark name, NutraSweet. However, one of the drawbacks of aspartame is its instability to heat and acid. Some interesting concepts related to aspartame are highlighted in the aspartame concept presented in figure.
