Metabolite Identification
Common Name12(S)-Leukotriene B4
Description12(S)-Leukotriene B4, also known as 12-epi-LTB4 or 12S-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, 12(S)-leukotriene B4 is considered to be an eicosanoid lipid molecule. 12(S)-Leukotriene B4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
