Stearaldehyde

Octadecyl aldehyde

C18H36O (268.2766)


Stearaldehyde or octadecanal is a normal long chain fatty aldehyde that can be found in total lipid extracts of muscle tissue. Stearaldehyde can also be found in the plasma of patients with Sjogren-Larsson syndrome. Sjogren-Larsson syndrome (SLS) is an autosomal recessively inherited neurocutaneous disorder caused by a deficiency of the microsomal enzyme fatty aldehyde dehydrogenase (FALDH). (PMID 14564703, 11408337). Octadecanal is often used as the substrate of choice to test FALDH activity in patients suspected of having Sjogren-Larsson syndrome.

meso-Pristane

Pristane(TM), synthetic 2,6,10,14-Tetramethylpentadecane Molecular biology reagent

C19H40 (268.313)


Pristane is a norterpene that is an acyclic saturated hydrocarbon derived from phytane by loss of its C-16 terminal methyl group. It has a role as a biomarker and an immunological adjuvant. It is a norterpene and a long-chain alkane. Pristane is a natural product found in Salvia officinalis, Sergia lucens, and Cynomorium songaricum with data available. Pristane is a natural or synthetic isoprenoid hydrocarbon (C19) derivative, Pristane is commonly used in research to prime the abdomen prior to hybridoma implantation in experimental animals. An irritant that induces granulomatous inflammation and interferes with local lymphatic drainage, it increases ascitic yields. Pristane has a low margin of safety and is toxic at levels slightly higher than used to prime animals. (NCI04) See also: Shark Liver Oil (part of). Meso-pristane, also known as 2,6,10,14-tetramethylpentadecane or norphytan, is a member of the class of compounds known as acyclic diterpenoids. Acyclic diterpenoids are diterpenoids (compounds made of four consecutive isoprene units) that do not contain a cycle. Meso-pristane can be found in fishes, which makes meso-pristane a potential biomarker for the consumption of this food product. meso-Pristane is found in fishes. meso-Pristane is isolated from fish liver oi D007155 - Immunologic Factors > D007166 - Immunosuppressive Agents D009676 - Noxae > D002273 - Carcinogens Pristane (Norphytane) is a naturally occurring hydrocarbon oil found in small quantities in many plants, in various marine organisms, and as the most active component of mineral oil[1]. Pristane is a non-antigenic adjuvant, and induces MHC class II-restricted, arthritogenic T cells in the rat[2].

Oleyl alcohol

cis-Laquo deltaraquo 9-octadecenol

C18H36O (268.2766)


Oleyl alcohol (also octadecenol or cis-9-octadecen-1-ol) is a non-ionic, unsaturated fatty alcohol. It is an emulsion stabilizer, antifoam agent, detergent, and release agent for food applications. Oleyl alcohol is found in fish oils and inedible beef fat. It belongs to the family of fatty alcohols. These are aliphatic alcohols consisting of a chain of 8 to 22 carbon atoms (do not have to bear a carboxylic acid group) (Wikipedia). Oleyl alcohol is an active compound. Oleyl alcohol can be used for various studies[1].

   

Nonadecane

Unknown branched fragment OF phospholipid

C19H40 (268.313)


Nonadecane, also known as CH3-[CH2]17-CH3, belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2 , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms. Nonadecane is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Thus, nonadecane is considered to be a hydrocarbon lipid molecule. Nonadecane is an alkane and bland tasting compound. nonadecane has been detected, but not quantified, in several different foods, such as pomes, watermelons, yellow bell peppers, allspices, and papaya. This could make nonadecane a potential biomarker for the consumption of these foods. Nonadecane has been linked to the inborn metabolic disorders including celiac disease. Isolated from apple wax. Nonadecane is found in many foods, some of which are pepper (c. annuum), red bell pepper, papaya, and dill.

6,10,14-trimethylpentadecan-2-one, also known as hexahydrofarnesylacetone, is a member of the class of compounds known as sesquiterpenoids. Sesquiterpenoids are terpenes with three consecutive isoprene units. 6,10,14-trimethylpentadecan-2-one is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 6,10,14-trimethylpentadecan-2-one is a celery, fat, and herbal tasting compound and can be found in a number of food items such as sweet basil, common oregano, roselle, and wild celery, which makes 6,10,14-trimethylpentadecan-2-one a potential biomarker for the consumption of these food products. Hexahydrofarnesyl acetone (6,10,14-Trimethyl-2-pentadecanone), a sesquiterpene isolated from Impatiens parviflora, is the major constituents of the essential oil.
