Common Name(9z,12s,13s)-12,13-dihydroxyoctadec-9-enoic acid
Description12,13-DHOME, also known as 12,13-dihome, 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. Thus, 12,13-dhome is considered to be an octadecanoid lipid molecule. (9z,12s,13s)-12,13-dihydroxyoctadec-9-enoic acid is found in Ipomoea nil. (9z,12s,13s)-12,13-dihydroxyoctadec-9-enoic acid was first documented in 2007 (PMID: 17435320). 12,13-DHOME is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
