2-Propylglutaric acid
CAS:2-Propylglutaric acid (2PGA) is a metabolic byproduct of the metabolism of branched chain amino acids. It is found in urine samples and has been shown to cause liver lesions in rats. 2PGA is metabolized to propionic acid, which can be detected in urine as a marker for renal dysfunction. 2PGA also increases gamma-aminobutyric acid levels in the brain and may have an effect on GABAergic neurotransmission. The elimination rate of 2PGA is slower than that of propionic acid, which means that it persists longer in the body than other metabolites. This chemical ionization technique can be used to measure the concentration of 2PGA and other fatty acids in biological fluids.

Formula:C22H24F2O5SPurity:Min. 95%Molecular weight:438.49 g/molMelatonin
CAS:Melatonin is a neurotransmitter produced by the pineal gland that is involved in the regulation of sleep-wake cycles. It can be used to treat several conditions like shift work disorders, insomnia, jet lag, and alterations of the circadian rhythm.

In an interesting research conducted on zebrafish, it was found that memory formation occurs better during daytime compared to nighttime, suggesting a role of melatonin in this process. When melatonin was administered during the daytime it caused reduced memory formation. On the contrary, removing the pineal gland or treating the fish with a melatonin antagonist significantly improves nighttime memory formation.Formula:C13H16N2O2Purity:Min. 98 Area-%Color and Shape:White Off-White PowderMolecular weight:232.28 g/molL-Methionine 4-nitroanilide
