Hexacosanoic acid-d4 is intended for use as an internal standard for the quantification of hexacosanoic acid by GC- or LC-MS. Hexacosanoic acid is a 26-carbon saturated (26:0) very-long-chain fatty acid. Plasma levels of hexacosanoic acid are increased in a mouse model of adrenoleukodystrophy, a peroxisomal disorder.1 Increased levels of hexacosanoic acid in red blood cells or in plasma positively correlated with atherosclerotic risk factors and metabolic syndrome, respectively.2,3
