Cholic acid-¹³C is the ¹³C-labeled Cholic acid. Cholic acid is a major primary bile acid produced in the liver and usually conjugated with glycine or taurine. It facilitates fat absorption and cholesterol excretion.

Linoleic Acid-d₄ is the deuterium labeled Linoleic acid. Linoleic acid is a common polyunsaturated (PUFA) found in plant-based oils, nuts and seeds. Linoleic acid is a part of membrane phospholipids, and functions as a structural component to maintain a certain level of membrane fluidity of the transdermal water barrier of the epidermis. Linoleic acid induces red blood cells and hemoglobin damage via oxidative mechanism .

Methyl heptadecanoate-d₃₃ is the deuterium labeled Methyl heptadecanoate (HY-W004290). Methyl heptadecanoate (C17:0 methyl ester) is the methyl ester derivative of heptadecanoic acid (HY-W004284). Methyl heptadecanoate is used as an internal standard for quantitative calibration of fatty acids in GC-MS analysis.

Glycoursodeoxycholic acid-d₄ (Ursodeoxycholylglycine-d₄) is the deuterium labeled Glycoursodeoxycholic acid. Glycoursodeoxycholic acid, a acyl glycine and a bile acid-glycine conjugate, is a metabolite of ursodeoxycholic acid.

Dinoprost-d₄ is the deuterium labeled Dinoprost. Dinoprost (Prostaglandin F2α) is an orally active, potent prostaglandin F (PGF) receptor (FP receptor) agonist. Dinoprost is a luteolytic hormone produced locally in the endometrial luminal epithelium and corpus luteum (CL). Dinoprost plays a key role in the onset and progression of labour.

γ-Aminobutyric acid-¹³C₄ is the ¹³C-labeled γ-Aminobutyric acid. γ-Aminobutyric acid (4-Aminobutyric acid) is a major inhibitory neurotransmitter in the adult mammalian brain, binding to the ionotropic GABA receptors (GABAA receptors) and metabotropic receptors (GABAB receptors).

Heptadecanoic acid-d₃₃ is the deuterium labeled Heptadecanoic acid. Heptadecanoic acid is an odd chain saturated fatty acid (OCS-FA). Heptadecanoic acid is associated with several diseases, including the incidence of coronary heart disease, prediabetes and type 2 diabetes as well as multiple sclerosis.

Palmitic acid-d₂ is the deuterium labeled Palmitic acid. Palmitic acid is a long-chain saturated fatty acid commonly found in both animals and plants. Palmitic acid can induce the expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in in mouse granulosa cells.

(±)-Jasmonic acid-d₅ is the deuterium labeled (±)-Jasmonic acid. (±)-Jasmonic acid is a plant growth regulator and a derivative of α-linolenic acid. (±)-Jasmonic acid decreases chlorophyll levels in green and etiolated barley leaf segments and inhibits elongation of rice seedlings.
