Chemical Information

FooDB Name

Eicosanic acid

Description

Arachidic acid, also known as eicosanoic acid or eicosanoate, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, arachidic acid is considered to be a fatty acid lipid molecule. Arachidic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Arachidic acid can be found in a number of food items such as chinese cinnamon, strawberry, winged bean, and thistle, which makes arachidic acid a potential biomarker for the consumption of these food products. Arachidic acid can be found primarily in blood and feces. Moreover, arachidic acid is found to be associated with schizophrenia.
