Chemical Information
FooDB NameSqualene
DescriptionSqualene, also known as (e,e,e,e)-squalene or all-trans-squalene, is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Squalene can be found in a number of food items such as apricot, savoy cabbage, peach (variety), and bitter gourd, which makes squalene a potential biomarker for the consumption of these food products. Squalene can be found primarily in blood, feces, and sweat, as well as throughout most human tissues. In humans, squalene is involved in several metabolic pathways, some of which include risedronate action pathway, steroid biosynthesis, alendronate action pathway, and fluvastatin action pathway. Squalene is also involved in several metabolic disorders, some of which include cholesteryl ester storage disease, CHILD syndrome, hyper-igd syndrome, and wolman disease. Squalene is a natural 30-carbon organic compound originally obtained for commercial purposes primarily from shark liver oil (hence its name, as Squalus is a genus of sharks), although plant sources (primarily vegetable oils) are now used as well, including amaranth seed, rice bran, wheat germ, and olives. Yeast cells have been genetically engineered to produce commercially useful quantities of "synthetic" squalene .

antioxidant22586 A substance that opposes oxidation or inhibits reactions brought about by dioxygen or peroxides. In European countries, E-numbers for permitted antioxidant food additives are from E 300 to E 324.DUKE

immunostimulant50847 A substance that augments, stimulates, activates, potentiates, or modulates the immune response at either the cellular or humoral level. A classical agent (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contains bacterial antigens. It could also be endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Its mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy is related to its antigen-specific immunoadjuvanticity.DUKE
lipoxygenase inhibitor35856 A compound or agent that combines with lipoxygenase and thereby prevents its substrate-enzyme combination with arachidonic acid and the formation of the icosanoid products hydroxyicosatetraenoic acid and various leukotrienes.DUKE
