Natural Product Identification
Common Namedl-9-hydroxy stearic acid
Description9-Hydroxyoctadecanoic acid, also known as 9-hydroxystearate or 18:0(9-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. dl-9-hydroxy stearic acid is found in Jodina rhombifolia. dl-9-hydroxy stearic acid was first documented in 2004 (PMID: 14715257). 9-Hydroxyoctadecanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (PMID: 15716589) (PMID: 16487928) (PMID: 16702808) (PMID: 17234448).
