Metabolite Identification
Common Name22-oxo-docosanoate
Description22-oxo-docosanoate, also known as 22-oxobehenate or 22-oxo-c22:0(1-), is a member of the class of compounds known as very long-chain fatty acids. Very long-chain fatty acids are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. 22-oxo-docosanoate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 22-oxo-docosanoate can be found in a number of food items such as strawberry guava, fig, sea-buckthornberry, and rowal, which makes 22-oxo-docosanoate a potential biomarker for the consumption of these food products.
