A coenzyme may either be attached by covalent bonds to a particular enzyme or exist freely in solution, but in either case it participates intimately in ..... Click the link for more information. . Glutathioneγ-glutamyl cysteinyl glycine, a tripep-tide formed from radicals of three amino acids—glutamic acid, cysteine, and glycine. A peculiarity of the structure of glutathione is the peptide bond between cysteine and glutamic acid, in which the γ-carboxyl of the glutamic acid participates. Glutathione is present in all living organisms and is very important for oxidation-reduction reactions in connection with the capacity of the sulfhydryl group (SH—) of cysteine to undergo the reversible reaction Glutathione can act as a coenzyme in the action of cathepsins, papain, and other proteolytic enzymes. The function of glutathione in metabolism apparently also includes the protection of the SH group of cytoplasm proteins against oxidation. glutathione[¦glüd·ə′thī‚ōn]glutathioneenUKglutathione[gloo″tah-thi´ōn]glu·ta·thi·one (GSH),(glū'tă-thī'ōn),See also: oxidized glutathione, reduced glutathione, glutathione reductase. glutathione(glo͞o′tə-thī′ōn′)glutathioneA ubiquitous tripeptide with antioxidant activity involved in CNS metabolism, serving as a coenzyme for some enzymes of oxidation-reduction systems, transmembrane amino acid transport, maintenance of red cell integrity and prevention of H2O2 accumulation in red cells.Glutathione-rich foods Asparagus, avocado, broccoli, oranges, squash, strawberries and watermelon. glutathioneγ-Glutamyl-cysteinyl-glycine A ubiquitous antioxidant tripeptide involved in CNS metabolism, which serves as a coenzyme for some enzymes of oxidation-reduction systems, transmembrane amino acid transport, maintaining RBC integrity, and prevention of H2O2 accumulation in RBCs.
