18E-20-oxo-20-CoA-LTB4
18E-20-oxo-20-CoA-LTB4 is formed when leukotriene B4 (LTB4) is metabolized by beta-oxidation. LTB4 is the major metabolite in neutrophil polymorphonuclear leukocytes. 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. The regulation of leukotriene production occurs at various levels, including expression of 5-LO, translocation of 5-LO to the perinuclear region and phosphorylation to either enhance or inhibit the activity of 5-LO. 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. (PMID: 8632343, 9667737). Leukotrienes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. 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. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. 18E-20-oxo-20-CoA-LTB4 is formed when leukotriene B4 (LTB4) is metabolized by beta-oxidation.

gentiodelphin
Gentiodelphin is a member of the class of compounds known as anthocyanidin 5-o-6-p-coumaroyl glycosides. Anthocyanidin 5-o-6-p-coumaroyl glycosides are anthocyanidin 5-O-glycosides where the carbohydrate moiety is esterified at the C6 position with a p-coumaric acid. P-coumaric acid is an organic derivative of cinnamic acid, that carries a hydroxyl group at the 4-position of the benzene ring. Gentiodelphin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Gentiodelphin can be found in a number of food items such as radish (variety), poppy, dandelion, and date, which makes gentiodelphin a potential biomarker for the consumption of these food products.
