1-Triacontanol
Triacontan-1-ol, also known as myricyl alcohol or triacontanyl alcohol, is a member of the class of compounds known as fatty alcohols. Fatty alcohols are aliphatic alcohols consisting of a chain of a least six carbon atoms. Thus, triacontan-1-ol is considered to be a fatty alcohol lipid molecule. Triacontan-1-ol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Triacontan-1-ol can be found in a number of food items such as coriander, common grape, tea, and cabbage, which makes triacontan-1-ol a potential biomarker for the consumption of these food products.
Squalene
Squalene is an unsaturated aliphatic hydrocarbon (carotenoid) with six unconjugated double bonds found in human sebum (5\\\\%), fish liver oils, yeast lipids, and many vegetable oils (e.g. palm oil, cottonseed oil, rapeseed oil). Squalene is a volatile component of the scent material from Saguinus oedipus (cotton-top tamarin monkey) and Saguinus fuscicollis (saddle-back tamarin monkey) (Hawleys Condensed Chemical Reference). Squalene is a component of adult human sebum that is principally responsible for fixing fingerprints (ChemNetBase). It is a natural organic compound originally obtained for commercial purposes primarily from shark liver oil, though there are botanical sources as well, including rice bran, wheat germ, and olives. All higher organisms produce squalene, including humans. It is a hydrocarbon and a triterpene. Squalene is a biochemical precursor to the whole family of steroids. Oxidation of one of the terminal double bonds of squalene yields 2,3-squalene oxide which undergoes enzyme-catalyzed cyclization to afford lanosterol, which is then elaborated into cholesterol and other steroids. Squalene is a low-density compound often stored in the bodies of cartilaginous fishes such as sharks, which lack a swim bladder and must therefore reduce their body density with fats and oils. Squalene, which is stored mainly in the sharks liver, is lighter than water with a specific gravity of 0.855 (Wikipedia) Squalene is used as a bactericide. It is also an intermediate in the manufacture of pharmaceuticals, rubber chemicals, and colouring materials (Physical Constants of Chemical Substances). Trans-squalene is a clear, slightly yellow liquid with a faint odor. Density 0.858 g / cm3. Squalene is a triterpene consisting of 2,6,10,15,19,23-hexamethyltetracosane having six double bonds at the 2-, 6-, 10-, 14-, 18- and 22-positions with (all-E)-configuration. It has a role as a human metabolite, a plant metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite. Squalene is originally obtained from shark liver oil. It is a natural 30-carbon isoprenoid compound and intermediate metabolite in the synthesis of cholesterol. It is not susceptible to lipid peroxidation and provides skin protection. It is ubiquitously distributed in human tissues where it is transported in serum generally in association with very low density lipoproteins. Squalene is investigated as an adjunctive cancer therapy. Squalene is a natural product found in Ficus septica, Garcinia multiflora, and other organisms with data available. squalene is a metabolite found in or produced by Saccharomyces cerevisiae.

7-Ketocholesterol
7-Ketocholesterol is a major oxidation product of cholesterol (oxysterol) found in human atherosclerotic plaque and is more atherogenic than cholesterol in some animal studies. Oxysterols (oxygenated forms of cholesterol) are present at low levels in the circulation and accumulate is plasma and tissues in some pathologies. In atherosclerotic lesions, 7-oxygenated oxysterols, predominantly 7-ketocholesterol, accumulate and have been implicated in the pathology of the disease. There is some in vivo and in vitro evidence that sterol 27-hydroxylase acts on 7-ketocholesterol to initiate its degradation to more polar, water-soluble products. Recent studies indicate an alternative mechanism, in which 7-ketocholesterol is reduced to 7 beta-hydroxycholesterol by 11 beta-hydroxysteroid dehydrogenase type 1. 7-Ketocholesterol can inhibit cholesterol 7 alpha-hydroxylase, the rate-limiting step in bile acid biosynthesis, as well as strongly inhibiting HMG-CoA reductase, the rate-limiting enzyme in cholesterol biosynthesis. It has even been suggested that 7-ketocholesterol is formed enzymically as an endogenous regulator of cholesterol biosynthesis. However, when tested as a pharmacological cholesterol-lowering agent, inhibition of HMG-CoA reductase was rapidly overcome and the 7-ketocholesterol metabolised. In vitro, 7-ketocholesterol has wide-ranging and potent effects, most of which have the potential to contribute to atherosclerosis. For example, 7-ketocholesterol can be cytotoxic and can induce apoptosis in vascular cells. These effects, either individually or more likely, in combination, all implicate 7-ketocholesterol in the initiation and development of atherosclerosis, but further work is needed to establish whether or not its role is a direct causal one. 7-Ketocholesterol is the second most abundant oxysterol found in human atherosclerotic plaque, after the enzymically formed 27-hydroxycholesterol (cholest-5-ene-3beta,27-diol). 7-Ketocholesterol differs from cholesterol by a ketone functional group present at the 7-position. It is produced from cholesterol via the epimeric cholesterol 7-hydroperoxides (cholest-5-ene-3beta-ol-7-hydroperoxide) which decompose to the epimeric 7-hydroxycholesterols (cholest-5-ene-3beta,7-diol) and 7-ketocholesterol. 7-Ketocholesterol is a major dietary oxysterol. It has also been widely suggested that 7-ketocholesterol present in atherosclerotic tissue may be derived from the diet. Certainly, 7-ketocholesterol is a major oxysterol found in cholesterol-rich processed foodstuffs. Dietary 7-ketocholesterol is rapidly metabolised by the liver to 7beta-hydroxycholesterol (cholest-5-ene-3beta,7beta-diol), unusual bile acids and perhaps even cholesterol itself. Its conversion to 7beta-hydroxycholesterol is well documented.

CE(14:0)
CE(14:0) is a cholesterol fatty acid ester or simply a cholesterol ester (CE). Cholesterol esters are cholesterol molecules with long-chain fatty acids linked to the hydroxyl group. They are much less polar than free cholesterol and appear to be the preferred form for transport in plasma and for storage. Cholesterol esters do not contribute to membranes but are packed into intracellular lipid particles or lipoprotein particles. Because of the mechanism of synthesis, plasma cholesterol esters tend to contain relatively high proportions of C18 fatty acids. Cholesterol esters are major constituents of the adrenal glands and they also accumulate in the fatty lesions of atherosclerotic plaques. Cholesterol esters are also major constituents of the lipoprotein particles carried in blood (HDL, LDL, VLDL). The cholesterol esters in high-density lipoproteins (HDL) are synthesized largely by transfer of fatty acids to cholesterol from position sn-2 (or C-2) of phosphatidylcholine catalyzed by the enzyme lecithin cholesterol acyl transferase (LCAT). The enzyme also promotes the transfer of cholesterol from cells to HDL. As cholesterol esters accumulate in the lipoprotein core, cholesterol is removed from its surface thus promoting the flow of cholesterol from cell membranes into HDL. This in turn leads to morphological changes in HDL, which grow and become spherical. Subsequently, cholesterol esters are transferred to the other lipoprotein fractions LDL and VLDL, a reaction catalyzed by cholesteryl ester transfer protein. Another enzyme, acyl-CoA:cholesterol acyltransferase (ACAT) synthesizes cholesterol esters from CoA esters of fatty acids and cholesterol. Cholesterol ester hydrolases liberate cholesterol and free fatty acids when required for membrane and lipoprotein formation, and they also provide cholesterol for hormone synthesis in adrenal cells.

Squalene
Squalene, 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 .
