Common Name | 15R-hydroxy-5Z,8Z,11Z,13E,17Z-eicosapentaenoic acid |
---|
Description | 15(R)-HEPE, also known as 15R-hepe, belongs to the class of organic compounds known as hydroxyeicosapentaenoic acids. These are eicosanoic acids with an attached hydroxyl group and five CC double bonds. Thus, 15(R)-hepe is considered to be an eicosanoid lipid molecule. 15(R)-HEPE is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. |
