The molecule is a prostanoid anion obtained by deprotonation of the three carboxy groups and protonation of the glutamyl alpha-amino group of (R)-PGJ2-S-glutathione conjugate; major species at pH 7.3. It derives from a prostaglandin J2(1-) and a glutathionate(1-). It is a conjugate base of a (R)-PGJ2-S-glutathione conjugate.
