Metabolite Identification
Common Namerac-5,6-Epoxy-retinoyl-beta-D-glucuronide
DescriptionRac-5,6-epoxy-retinoyl-beta-d-glucuronide is a member of the class of compounds known as diterpene glycosides. Diterpene glycosides are diterpenoids in which an isoprene unit is glycosylated. Rac-5,6-epoxy-retinoyl-beta-d-glucuronide is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Rac-5,6-epoxy-retinoyl-beta-d-glucuronide can be found primarily in blood and urine, as well as in human kidney and liver tissues. Within the cell, rac-5,6-epoxy-retinoyl-beta-d-glucuronide is primarily located in the membrane (predicted from logP). This compound belongs to the family of Diterpene Glycosides.
