Chemical Information
FooDB NameStearaldehyde
DescriptionStearaldehyde or octadecanal is a normal long chain fatty aldehyde that can be found in total lipid extracts of muscle tissue. Stearaldehyde can also be found in the plasma of patients with Sjogren-Larsson syndrome. Sjogren-Larsson syndrome (SLS) is an autosomal recessively inherited neurocutaneous disorder caused by a deficiency of the microsomal enzyme fatty aldehyde dehydrogenase (FALDH). (PMID 14564703, 11408337). Octadecanal is often used as the substrate of choice to test FALDH activity in patients suspected of having Sjogren-Larsson syndrome. [HMDB]
