Common Name | 12-Oxo-10,11-dihydro-20-carboxy-leukotriene B4 |
---|
Description | 12-Oxo-10,11-dihydro-20-COOH-LTB4, also known as 12-oxo-10,11-dihydro-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-10,11-dihydro-20-COOH-LTB4 is considered to be an eicosanoid lipid molecule. 12-Oxo-10,11-dihydro-20-COOH-LTB4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 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. Leukotrienes are eicosanoids. Leukotrienes are metabolites of arachidonic acid derived from the action of 5-LO (5-lipoxygenase). The immediate product of 5-LO is LTA4 (leukotriene A4), which is enzymatically converted into either LTB4 (leukotriene B4) by LTA4 hydrolase or LTC4 (leukotriene C4) by LTC4 synthase. Biologically active LTB4 is metabolized by w-oxidation carried out by specific cytochrome P450s (CYP4F) followed by beta-oxidation from the w-carboxy position and after CoA ester formation. All mammalian cells except erythrocytes synthesize eicosanoids. |
