Metabolite Identification
Common Name5-HEPE
Description5-HEPE is a major eicosanoid formed from eicosapentaenoic acid (EPA). 5-HEPE is produced in human neutrophils. The eicosanoids are a diverse family of molecules that have powerful effects on cell function. They are best known as intercellular messengers, having autocrine and paracrine effects following their secretion from the cells that synthesize them. The diversity of possible products that can be synthesized from eicosatrienoic acid is due, in part to the variety of enzymes that can act on it. Studies have placed many, but not all, of these enzymes at or inside the nucleus. In some cases, the nuclear import or export of eicosatrienoic acid-processing enzymes is highly regulated. Furthermore, nuclear receptors that are activated by specific eicosanoids are known to exist. (PMID: 8847485 , 15896193 ).
