| Common Name | Dihydroxystearic acid |
|---|
| Description | Dihydroxystearic acid, also known as dihydroxystearate, 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. Dihydroxystearic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Dihydroxystearic acid can be found in peanut, which makes dihydroxystearic acid a potential biomarker for the consumption of this food product. |
