CC   -!- FUNCTION: Could play a major role in protecting mammals from the
CC       toxicity of ingested organic hydroperoxides. Tert-butyl hydroperoxide,
CC       cumene hydroperoxide and linoleic acid hydroperoxide but not
CC       phosphatidycholine hydroperoxide, can act as acceptors.
CC       {ECO:0000250|UniProtKB:P18283}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a hydroperoxide + 2 glutathione = an alcohol + glutathione
