Sulfonates are organosulfur compounds with sulfur in the oxidation state +5 generally linked to a terminal carbon atom (R-CH2-SO3H). Naturally occuring sulfonates are usually non-aromatic and include taurine (2-aminoethanesulfonate), which is found abundantly in mammals (Huxtable, 1992), isethionate (2-hydroxyethanesulfonate), which occurs in red algae (Holst, 1994), the squid axon (Koechlin, 1954) and in mammals as a result of taurine conversion, cysteate (DL-2-amino-3-sulfopropionate), which is derived from cysteine, the archaebacterial coenzyme M (2-mercaptoethanesulfonate), the membrane constituents sulfonolipids, and methanesulfonate, which is discussed below. Synthetic sulfonates commonly have an aromatic nucleus, for example in the linear alkylbenzene sulfonate surfactants (LAS) or the sulfonated dyestuffs (Kertesz et al. 1994). Some of the artificial buffers used in the laboratory are sulfonates like 3-(cyclohexylamino)-1-propanesulfonic acid (CAPS), 4-(2-hydroxyethyl)piperazine-l-ethanesulfonic acid (HEPES) and 3-morpholinopropanesulfonic acid (MOPS).
