The amino sulfonic acid taurine (CHEBI:15891, also known as 2-aminoethanesulfonic acid) gets its name from taurus, the Latin name for bull or ox, as it was from ox bile that the compound was first isolated by Friedrich Tiedemann (1781–1861) and Leopold Gmelin (1788–1853) while working at the University of Heidelberg in 1827 [1]. Among the general public it is probably best known as an additive in many energy drinks, but while some studies suggest that taurine supplements may improve athletic performance, a 2008 review concluded that the amount of taurine present in these drinks was "far below the amounts expected to deliver either therapeutic benefits or adverse events" [2]. Taurine is also known as an additive in some contact lens solutions – it inhibits protein denaturation, so may decrease protein binding to contact lenses [3,4].
