WebGlutathione is needed for the detoxification of methylglyoxal, a toxin produced as a by-product of the carbohydrate metabolism. Thus, the glyoxalase enzyme system catalyzes the conversion of methylglyoxal and reduced glutathione to s-d-lactoyl-glutathione, and the subsequent hydrolysis of s-d-lactoyl-glutathione to glutathione and lactic acid. 5. Glutathione is an antioxidant in plants, animals, fungi, and some bacteria and archaea.
