| Common Name | Gamma-Caprolactone |
|---|
| Description | Gamma-Caprolactone, also known as 4-ethyl-4-butanolide or 4-hexanolide, 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. It is occasionally found as a volatile component of human urine. In some cases differences up to an order of magnitude are observed. It has been also found in the polar fraction of human blood. |
