Metabolite Identification
Common Name20-Hydroxy-leukotriene B4
Description20-Hydroxy-leukotriene B4, also known as 20-OH-LTB4 or 20-hydroxy-LTB4, belongs to the class of organic compounds known as leukotrienes. These are eicosanoids containing a hydroxyl group attached to the aliphatic chain of an arachidonic acid. Leukotrienes have four double bonds, three (and only three) of which are conjugated. Thus, 20-hydroxy-leukotriene B4 is considered to be an eicosanoid lipid molecule. 20-Hydroxy-leukotriene B4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
