Autor: J. Guillaud, Yves Menezo, P. Guérin, C. Guyader-Joly, Jean-Paul Renard, S. Ponchon

Publikováno v: Amino Acids. 15:27-42

Two precursors of taurine have been studied: cysteamine and hypotaurine. Cysteamine has been quantified in genital secretions and found in follicular fluids of all species tested. On the contrary cysteamine was not detected (or traces) in tubal fluid
