Taurine (2-aminoethanesulphonic acid), a sulphur-containing amino acid, is found in most mammalian tissues. Although it can be synthesized from methionine and cysteine in the presence of vitamin B6, taurine can be obtained from the natural dietary sources. Taurine has many fundamental biological roles which are explained with amino terminal group in the structure and sulfonic acid group moiety.

As public consumer demand for taurine has increased, commercial production of the substance has become necessary, with the introduction of chemical synthesis. Taurine is often included as an ingredient in energy drinks, which is most likely due to its physiological effect to improve muscular function and physical performance.
