Possible Interaction: Methionine and Taurine

“ Methionine intakes above approximately 1 g/d transiently raise plasma Tau , Hcy, and GSH.”

“ Taurine can decrease methionine by decreasing uptake.”

“ Methionine was also markedly elevated, and taurine concentrations were significantly decreased.”

“ Taurine also reduced the extent of 3H-methyl group incorporation from radioactive methionine into myocardial phospholipids by −45%.”

“Accordingly, the taurine content of PV hepatocytes tended to be higher and to increase faster during incubation with methionine.”

“Supplementation of the diet containing 100 g pectin/kg with methionine (10 g/kg) and taurine (10 and 50 g/kg) strikingly increased hepatic taurine concentrations.”

“ Taurine concentration in liver decreased in cats fed excess MET and appeared to depend on taurine intake.”

“The diet that contained pea protein concentrate plus added methionine produced significantly lower plasma levels of methionine, arginine, proline, threonine, leucine, and taurine than the control values.”

“ Methionine … taurine in the liver while supplemental sulfate enhanced the activity of the sulfate activating enzymes and the in vitro synthesis of PAP35 S. The data … least a part of the growth response obtained by sulfate supplementation is due to the reactions whereby activated sulfate is converted to taurine.”
