Book excerpt: Taurine (2-aminoethanesulfonic acid) is an enigmatic compound abounding in animal tissues. Some of its physiological functions are already established, but the cellular mechanisms are still mostly a matter of conjecture. The 15th International Taurine Meeting offered a multidisciplinary symposium, with participants representing a range of fields of biological science. Based on the proceedings of this meeting, Taurine 6: Taurine Today presents current research on Taurine by top scientists in the field.
