what enzyme makes glutathione Schematic representation of the role of the reductase glutathione peroxidase cofactor The effectiveness

Glutamine is a neutral amino acid and thus does not induce a negative charge burden in the mitochondrial matrix, which is already more negatively charged than the cytosol

[20] [7] This conversion is illustrated by the reduction of peroxides (via the sulfenate as an intermediate): GSH + R 2 O 2 GSOR + ROH GSOR + GSH GSSG + ROH Net reaction: 2 GSH + R 2 O 2 GSSG + 2 ROH (R = H, alkyl) and with free radicals, forming glutathionyl radicals (GS ) that may dimerize to disulfide: GSH + R RH + GS 1/2 GSSG Thiyl radicals (such as glutathionyl radicals) are themselves oxidizing species in biology, with a single-electron reduction potential sufficient for oxidation of nucleic acids, proteins and polyunsaturated lipids
