Atrazine mercapturate is a major, glutathione-derived metabolite of atrazine , an herbicide that is effective in controlling a broad range of weeds. Atrazine has been reported to cause cancer in certain laboratory animals, have diverse effects on the reproductive system in animals and humans, and disrupt the normal function of the endocrine system. Atrazine mercapturate is readily measured in urine samples.

Isoprostanes are prostaglandin (PG)-like products of free-radical induced lipid peroxidation. Although the isoprostanes derived from arachidonic acid are the best characterized, many other polyunsaturated fatty acids can form isoprostanes. (±)5-iPF2α-VI is one of dozens of possible stereo- and regioisomeric isoprostanes which can be formed from arachidonic acid. To date, the most extensively studied of these is 8-isoprostane (8-epi-PGF2α, iPF2α-III). However, 8-isoprostane is a minor isoprostane constituent when compared to some of the other isomers which form in natural conditions of oxidative stress. (±)5-iPF2α-VI is an isoprostane from the unique Type VI class of isoprostanes. This class has been shown to be one of the major isoprostane products, in contrast to 8-isoprostane. In addition to being produced in greater abundance than 8-isoprostane, Type VI isoprostanes form internal lactones, which facilitates their extraction and purification from biological samples.

Eicosapentaenoic acid is metabolized, in part, through cytochrome P450-catalyzed epoxidation followed by conversion to the vicinal diols by epoxide hydrolases.

While its biological activity is unknown, the selective capacity of (±)5(6)-DiHETE to form this lactone can be utilized to specifically quantify (±)5(6)-DiHETE in biological samples.

4-Methylumbelliferyl-β-D-N,N',N''-triacetylchitotrioside is a fluorogenic substrate for chitinases and chitotriosidases. 4-Methylumbelliferyl-β-D-N,N',N''-triacetylchitotrioside is cleaved by chitinases and chitotriosidases to release the fluorescent moiety 4-methylumbelliferyl (4-MU). 4-MU fluorescence is pH-dependent with excitation maxima of 320 and 360 nm at low (1.97-6.72) and high (7.12-10.3) pH, respectively, and an emission maximum ranging from 445 to 455 nM, increasing as pH decreases. It has been used to screen plasma samples for reduced chitotriosidase activity that may be indicative of lysosomal storage disorders.

Petromyzonol is a tetrahydroxy stearol which serves as the primary spawning pheromone in adult sea lamprey. It is produced in the bile of sea lamprey larvae from the bile acid precursor allocholic acid. While the adult sea lamprey is relatively insensitive to petromyzonol itself, the C-24 sulfate ester (petromyzonol sulfate) is a pheromone and a spawning chemoattractant which can be detected at very low concentrations by lamprey olfactory chemoreceptors. Petromyzonol, petromyzonol sulfate, and allocholic acid are all found in water samples from fresh water streams bearing larval lamprey populations.[1]

Sphinganine-1-phosphate (d17:0) is a sphingolipid analog of sphinganine-1-phosphate (d18:0) and sphingosine-1-phosphate (d18:1) that has a 17-carbon base.

C16 Sphingosine-1-phosphate (C16 S1P) is a derivative of sphingosine-1-phosphate that binds to S1P1/EDG-1, S1P3/EDG-3, and S1P2/EDG-5 receptors with affinities of 115%, 83%, and 103%, respectively, relative to S1P in CHO cells. C16 S1P was increased in postmortem primary open angle glaucoma trabecular meshwork samples.
