CC   -!- FUNCTION: Protects cells and enzymes from oxidative damage, by
CC       catalyzing the reduction of hydrogen peroxide, lipid peroxides and
CC       organic hydroperoxide, by glutathione. {ECO:0000250|UniProtKB:O70325}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a hydroperoxy polyunsaturated fatty acid + 2 glutathione = a
CC         hydroxy polyunsaturated fatty acid + glutathione disulfide + H2O;
CC         Xref=Rhea:RHEA:19057, ChEBI:CHEBI:15377, ChEBI:CHEBI:57925,

CC         EC=1.11.1.12; Evidence={ECO:0000250|UniProtKB:P36968};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the glutathione peroxidase family.
CC       {ECO:0000305}.
