Natural Product Identification
Common Name12-Oxo-20-carboxy-leukotriene B4
Description12-Oxo-20-carboxy-leukotriene B4, also known as 12-oxo-20-carboxy-LTB(,4), belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, 12-oxo-20-carboxy-leukotriene B4 is considered to be an eicosanoid lipid molecule. 12-Oxo-20-carboxy-leukotriene B4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. LTB4 is the major metabolite in neutrophil polymorphonuclear leukocytes. The PGs and TXs are collectively identified as prostanoids. Leukotrienes are eicosanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes) and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids.
