4508 Phytanic acid Phytanic acid is a 20-carbon branched chain fatty acid, Phytanic acid is present in animal (primarily herbivores or omnivores) tissues where it may be derived from the chlorophyll in consumed plant material. Phytanic acid derives from the corresponding alcohol, phytol, and is ultimately oxidized into pristanic acid. In phytanic acid storage disease (Refsum disease) this lipid may comprise as much as 30% of the total fatty acids in plasma. These high levels in Refsum disease (a neurological disorder) are due to a phytanic acid alpha-hydroxylase deficiency. 14721-66-5 26840 C20H40O2 White powder. No indication of carcinogenicity to humans (not listed by IARC). This is an endogenously produced metabolite found in the human body. It is used in metabolic reactions, catabolic reactions or waste generation. 2014-08-29T06:51:24Z 2026-04-05T15:28:05Z Phytanic acid C01607 16285 true CC(C)CCCC(C)CCCC(C)CCCC(C)CC(O)=O C20H40O2 InChI=1S/C20H40O2/c1-16(2)9-6-10-17(3)11-7-12-18(4)13-8-14-19(5)15-20(21)22/h16-19H,6-15H2,1-5H3,(H,21,22) RLCKHJSFHOZMDR-UHFFFAOYSA-N 312.5304 312.302830524 Endogenous Solid HMDB00801 25001 Karrer, P.; Epprecht, A.; Konig, Hans.
