Metabolite Identification
Common Name3-Hexaprenyl-4-hydroxy-5-methoxybenzoic acid
Description3-Hexaprenyl-4-hydroxy-5-methoxybenzoic acid, also known as 3-hexaprenyl-4-hydroxy-5-methoxybenzoic acid, belongs to the class of organic compounds known as 2-polyprenyl-6-methoxyphenols. 2-polyprenyl-6-methoxyphenols are compounds containing a polyisoprene chain attached at the 2-position of a 6-methoxyphenol group. 3-Hexaprenyl-4-hydroxy-5-methoxybenzoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 3-Hexaprenyl-4-hydroxy-5-methoxybenzoic acid exists in all eukaryotes, ranging from yeast to humans. In cattle, 3-hexaprenyl-4-hydroxy-5-methoxybenzoic acid is involved in the metabolic pathway called ubiquinone biosynthesis pathway.
