The molecule is an icosanoid that is (6E,8Z,11Z,14Z,16E)-icosa-6,8,11,14,16-pentaenoic acid substituted at positions 5S and 18 by hydroperoxy and hydroxy groups respectively. It has a role as a human xenobiotic metabolite. It is a lipid hydroperoxide and a hydroperoxy(hydroxy)icosapentaenoic acid. It is a conjugate acid of a (5S)-hydroperoxy-18-hydroxy-EPE(1-).
