C18H26O6 (338.1729)

Pinolidoxin, also known as lethaloxin, is a member of the class of compounds known as oxocins. Oxocins are compounds containing an oxocin ring, which is a eight-member unsaturated aromatic ring containing one oxygen atom and seven carbon atoms. Pinolidoxin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Pinolidoxin can be found in common pea, which makes pinolidoxin a potential biomarker for the consumption of this food product.

Omega-Carboxy-trinor-leukotriene B4

(4Z,7S,8E,10E,12Z,14R)-7,14-dihydroxyoctadeca-4,8,10,12-tetraenedioic acid

C18H26O6 (338.1729)

omega-Carboxy-trinor-leukotriene B4 belongs to the leukotriene family. 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. omega-Carboxy-trinor-leukotriene B4 belongs to the leukotriene family

18-carboxy dinor Leukotriene B4

7,14-dihydroxyoctadeca-4,8,10,12-tetraenedioic acid

C18H26O6 (338.1729)

18-carboxy dinor Leukotriene B4, also known as 18-COOH-19,20-LTB4, is classified as a member of the Long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. 18-carboxy dinor Leukotriene B4 is considered to be practically insoluble (in water) and acidic
