Glutathione

γ-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

[gloo″tah-thi´ōn] a tripeptide of glutamic acid, cysteine, and glycine; the reduced form (GSH) serves as a reducing agent in many biochemical reactions, being converted to oxidized glutathione (GSSG) in which the cysteine residues of two glutathione molecules are connected by a disulfide bridge. Reduced glutathione is important in protecting erythrocytes from oxidation and hemolysis; deficiency causes sensitivity to oxidant drugs.

glu·ta·thi·one (GSH),

(glū'tă-thī'ōn), A tripeptide of glycine, l-cysteine, and l-glutamate, with l-glutamate having an isopeptide bond with the amino moiety of l-cysteine. Glutathione has a wide variety of roles in a cell; it is the most prevalent non-protein thiol. Glutathione disulfide (GSSG) consists of two glutathiones linked through a disulfide bridge; the term oxidized glutathione for GSSG should be avoided because it includes the sulfones and sulfoxides. (The term reduced glutathione is not necessary because glutathione is the thiol form.) A deficiency of glutathione can cause hemolysis with oxidative stress. It is also used in the course of intermediary metabolism as a donor of thiol (SH) groups and is essential for detoxification of acetaminophen.
See also: oxidized glutathione, reduced glutathione, glutathione reductase.

glutathione

A 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.

glu·ta·thi·one

(GSH) (glū'tă-thī'ōn) 1. The principal low molecular weight thiol compound of living plant cells; used in the course of intermediary metabolism as a donor of thiol (SH) groups; essential for detoxification of acetaminophen. 2. Compound has a wide variety of roles in a cell. A deficiency can cause hemolysis with oxidative stress.

glutathione

A tripeptide amino acid derivative that protects red cells from oxidative damage and, in the form of the enzyme glutathione peroxidase, plays an important role in detoxifying hydrogen peroxide and organic peroxides produced in the body. Glutathione also participates in the transport of amino acids from one cell to another.
