α-Angelica lactone has cardiotonic activity, may exert their effects by providing an increased contraction-dependent calcium pool to be released upon systolic depolarization.

3-Phenylbutyric acid undergoes metabolism through initial oxidation processes involving both its benzene ring and side chain. It serves as an effective agent for the isolation of Rhodococcus rhodochrous PB1 from compost soil.

2-Ketoglutaric acid Sodium (AKG) is a key molecule in the TCA cycle. It can be produced from glutamate by oxidative deamination via glutamate dehydrogenase and as a product of pyridoxal phosphate-dependent transamination reactions (mediated by branched-chain amino acid transaminases) in which glutamate is a common amino donor.

2-Ketoglutaric acid is a reversible inhibitor of tyrosinase (IC50=15 mM). 2-Ketoglutaric acid is an intermediate of the Krebs cycle and can produce either ATP or GTP. 2-Ketoglutaric acid also acts as a major carbon backbone for the nitrogen assimilation reaction.

4-Chlorocatechol, a significant degradation product of 4-chloro-2-aminophenol (4C2AP), serves as a substrate for both catechol 1,2-dioxygenases and chlorocatechol dioxygenase [1] [2].

γ-Hexalactone (γ-caprolactone) belongs to the class of organic compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. Thus, Gamma-caprolactone is considered to be a fatty ester lipid molecule. Gamma-Caprolactone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Gamma-Caprolactone exists in all eukaryotes, ranging from yeast to humans. Outside of the human body, Gamma-caprolactone has been detected, but not quantified in, several different foods, such as potato, cereals and cereal products, pomes, alcoholic beverages, and fruits. This could make Gamma-caprolactone a potential biomarker for the consumption of these foods. 4-hydroxy-Hexanoic acid gamma-lactone is occasionally found as a volatile component of human urine. In some cases differences up to an order of magnitude are observed. 4-hydroxy-Hexanoic acid gamma-lactone has been found in the polar fraction of human blood. Biological fluids such as blood and urine have been shown to contain a large number of components, some of them volatiles (low boiling point) apparently present in all individuals, while others such are much more variable. Although some of these changes may have dietary origins, others seem to be characteristic of the individual.

Jacaric acid is a conjugated polyunsaturated fatty acid first isolated from seeds of Jacaranda plants. Structurally, it is an 18-carbon ω-6 triene isomer of γ-linolenic acid . Jacaric acid induces cell cycle arrest and apoptosis in a variety of cancer cell lines (GI50 = 1-5 μM). It increases the production of reactive oxygen species, and cytotoxicity is abolished by the antioxidant α-tocopherol, suggesting that apoptosis results from oxidative stress. Jacaric acid is metabolized in vivo to conjugated linoleic acid , which is also cytotoxic to cancer cells. Jacaric acid inhibits cyclooxygenase-1 in vitro (Ki = 1.7 μM) and, with long term feeding, decreases stearoyl-CoA desaturase expression and activity in mice.

Sugammadex is an agent for reversal of neuromuscular blockade by the agent rocuronium in general anaesthesia. It is the first selective relaxant binding agent (SRBA). Sugammadex is a modified γ-cyclodextrin, with a lipophilic core and a hydrophilic periph

Dihomo-γ-linolenic acid (DGLA; all-cis-8,11,14-Eicosatrienoic acid) sodium, a 20-carbon ω-6 fatty acid, exhibits anti-inflammatory and anti-proliferative properties. It has been shown to mitigate atherosclerosis in the apolipoprotein E deficient mouse model system [1] [2] [3].

Glutamate decarboxylase is an enzyme that catalyzes the decarboxylation of glutamic acid to γ-aminobutyric acid (GABA) and carbon dioxide (CO2). Many gut microbes metabolize glutamic acid in a pyridoxal-5′-phosphate (PLP) dependent manner through their glutamate decarboxylase.
