DescriptionTaurine, also known as 2-sulfoethylamine or taufon, belongs to the class of organic compounds known as organosulfonic acids. Organosulfonic acids are compounds containing the sulfonic acid group, which has the general structure RS(=O)2OH (R is not a hydrogen atom). Taurine is a very strong basic compound (based on its pKa). Taurine exists in all living species, ranging from bacteria to humans. Taurine is a potentially toxic compound.
