Application Notes:
3-Hydroxyheptadecanoic acid is a high purity standard that is ideal as a standard or for biological systems. This odd
numbered fatty acid is unusual in many biological systems and can therefore be used as a biomarker. 3-
Hydroxyheptadecanoic acid has been used to characterize certain bacteria such as some gliding bacteria.1 3-Hydroxy fatty
acids have been found to be converted to the omega-fatty acid by the enzyme CYP4F11 and then into dicarboxylic acids in
vivo.2 3-hydroxy fatty acids are used as biomarkers for fatty acid oxidative disorders of both the long- and short-chain 3-
hydroxy-acyl-CoA dehydrogenases.3,4
