Solubility	SOL. IN CYCLOHEXANE,METHANOL Corey_EJ et al.. STABILITIES : to decompose to 5,12-DIHYDROXY-6,8,10,14-EICOSATETRAENOIC ACID and 5,6-DIHYDROXY-7,9,11,14-EICOSATETRAENOIC ACID under neutral aqueous solution at 37°C with one minite of half-life BorgeatPet al..
Source	Leukotriene A4 is produced as an intermediate for the biosyntheses of leukotrienes B4 and C4 in polymorphonuclear leukocytes, mast cells and macrophages of various animal species Hammarstrom_S .
Chemical Synthesis	Corey_EJ et al.
Metabolism	Arachidonate 5-lipoxygenase is a bifunctional enzyme with a 5-oxygenase activity converting arachidonic acid to 5-hydroperoxy-6,8,11,14-eicosatetraenoic acid and a leukotriene A synthase activity converting the 5-hydroperoxy acid to leukotriene A4. The same enzyme produces leukotriene A4 from arachidonic acid via 5-hydroperoxy acid Ford-Hutchinson_AW et al.. The produced leukotriene A4 ia converted either to leukotriene B4 or to leukotriene C4 Hammarstrom_S .
