S-Adenosylmethionin, kurz SAM oder AdoMet genannt, ist eine chemische Verbindung aus der Stoffklasse der Sulfonium-Betaine. SAM ist ein Schlüsselprodukt im Stoffwechsel der Aminosäure Methionin und entsteht durch eine Reaktion von Methionin mit Adenosintriphosphat (ATP). S-Adenosyl-L-methionine (SAMe) is a physiologic precursor of thiols and sulfurated compounds, which are known to be decreased in patients with liver disease. The effect of its administration on the hepatic glutathione content of liver patients was investigated.
