Metabolite Identification
Common Name2-hydroxyphytanic acid
Description2-hydroxyphytanic acid, also known as α-hydroxyphytanate, belongs to the class of organic compounds known as acyclic diterpenoids. These are diterpenoids (compounds made of four consecutive isoprene units) that do not contain a cycle. 2-hydroxyphytanic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
