Solubility	METHANOL Corey_EJ et al.
Source	Leukotriene B4 is produced by polymorphonuclear leukocytes and macrophages of various animal species upon various stimulations on the cells Samuelsson_B et al. Hammarstrom_S .
Chemical Synthesis	Corey_EJ et al.
Metabolism	Arachidonic acid is metabolized to leukotrienen A4 with 5,6-epoxide by 5-lipoxygenases, and the product is further transformed to leukotrienee B4 by leukotriene A hydrolase Ford-Hutchinson_AW et al.. Leukotriene B4 is metabolized to lose its bioactivities either by w-oxidation Hammarstrom_S or by leukotriene B4 12-hydroxydehydrogenase Yokomizo_T et al..
