| Common Name | 2(R)-hydroxydocosanoic acid |
|---|
| Description | 2(R)-hydroxydocosanoic acid, also known as a-hydroxybehenate or a-hydroxydocosanoate, belongs to the class of organic compounds known as very long-chain fatty acids. These are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. 2(R)-hydroxydocosanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. |
