It has a role as a mammalian metabolite. It is a branched-chain saturated fatty acid, a long-chain fatty acid, a methyl-branched fatty acid and a hydroxy fatty acid. It is functionally related to a phytanic acid. It is a conjugate acid of an omega-hydroxyphytanate. It derives from a hydride of a phytane."}]
