Common Name | 13-hydroxyoctadecanoic acid |
---|
Description | 13-hydroxyoctadecanoic acid, also known as 13-hydroxystearate or 18:0(13-OH), belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. 13-hydroxyoctadecanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. |
