Natural Product Identification
Common NameStearaldehyde
DescriptionStearaldehyde, also known as 1-octadecanal, belongs to the class of organic compounds known as fatty aldehydes. These are long chain aldehydes with a chain of at least 12 carbon atoms. Thus, stearaldehyde is considered to be a fatty aldehyde lipid molecule. Stearaldehyde is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Stearaldehyde is an oily tasting compound. Outside of the human body, Stearaldehyde has been detected, but not quantified in, evergreen blackberries. Stearaldehyde is found in Amphimedon compressa, Aplysina fistularis, Chrysanthemum indicum, Commiphora rostrata, Daphne odora, Mangifera indica, Mikania cordifolia, Pelargonium endlicherianum, Plumeria rubra, Stichodactyla helianthus and Tripneustes ventricosus. Stearaldehyde was first documented in 1967 (PMID: 14564703). This could make stearaldehyde a potential biomarker for the consumption of these foods.
