Chemical Information
FooDB Name16-Hydroxy-hexadecanoic acid
Description16-hydroxy-hexadecanoic acid, also known as 16-hydroxypalmitic acid or 16-oh 16:0, 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, 16-hydroxy-hexadecanoic acid is considered to be a fatty acid lipid molecule. 16-hydroxy-hexadecanoic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 16-hydroxy-hexadecanoic acid can be synthesized from hexadecanoic acid. 16-hydroxy-hexadecanoic acid is also a parent compound for other transformation products, including but not limited to, (3R)-3,16-dihydroxypalmitic acid, oscr#28, and 16-hydroxyhexadecanoyl-CoA. 16-hydroxy-hexadecanoic acid can be found in a number of food items such as other cereal product, hyacinth bean, red rice, and elliott's blueberry, which makes 16-hydroxy-hexadecanoic acid a potential biomarker for the consumption of these food products.
