Metabolite Identification
Common Name3-Hexaprenyl-4,5-Dihydroxybenzoic acid
Description3-Hexaprenyl-4,5-dihydroxybenzoic acid, also known as 3-hexaprenyl-4,5-dihydroxybenzoic acid or 3-hexaprenyl-4,5-dihydroxybenzoic acid, belongs to the class of organic compounds known as polyprenylbenzene-1,2-diols. Polyprenylbenzene-1,2-diols are compounds containing a polyisoprene chain attached to a catechol group. 3-Hexaprenyl-4,5-dihydroxybenzoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 3-Hexaprenyl-4,5-dihydroxybenzoic acid exists in all eukaryotes, ranging from yeast to humans. In cattle, 3-hexaprenyl-4,5-dihydroxybenzoic acid is involved in the metabolic pathway called ubiquinone biosynthesis pathway.
