4beta-(hydroxymethyl)-4alpha-methyl-5alpha-cholest-7-en-3beta-ol

alpha-Tocopherol is traditionally recognized as the most active form of vitamin E in humans and is a powerful biological antioxidant. The measurement of "vitamin E" activity in international units (IU) was based on fertility enhancement by the prevention of spontaneous abortions in pregnant rats relative to alpha-Tocopherol. Natural vitamin E exists in eight different forms or isomers: four tocopherols and four tocotrienols. In foods, the most abundant sources of vitamin E are vegetable oils such as palm oil, sunflower, corn, soybean, and olive oil. Nuts, sunflower seeds, and wheat germ are also good sources.

4alpha-hydroxymethyl-4beta-methyl-5alpha-cholesta-8-en-3beta-ol is a 3-beta-hydroxysterol that is an intermediate in cholesterol biosynthesis II (via 24,25-dihydrolanosterol). It is a substrate for C-4 methyl sterol oxidase (SC4MOL) and can be generated from the enzymatic reduction of 4alpha-formyl-4beta-methyl-5alpha-cholesta-8-en-3beta-ol or from the enzymatic oxidation of 4,4-dimethyl-5alpha-cholesta-8-en-3-beta-ol. The sequence of reactions and the types of intermediates in cholesterol biosynthesis may vary. Alternate routes exist because reduction of the carbon 24,25 double bond on the hydrocarbon side chain of the sterol ring structure by sterol delta24-reductase can occur at multiple points in the pathway, giving rise to different intermediates. These intermediates, with or without a double bond in the hydrocarbon side chain, can serve as substrates for the other enzymes in the pathway.

4-beta-hydroxymethyl-4-alpha-methyl-5-alpha-cholest-7-en-3-beta-ol is part of the Steroid biosynthesis pathway. It is a substrate for: Methylsterol monooxygenase 1, and Methylsterol monooxygenase 1.

4α-hydroxymethyl-4β-methyl-5α-cholesta-8-en-3β-ol is considered to be practically insoluble (in water) and relatively neutral. 4α-hydroxymethyl-4β-methyl-5α-cholesta-8-en-3β-ol is a sterol lipid molecule

(S,S,S)-alpha-tocopherol is the (S,S,S)-stereoisomer of alpha-tocopherol. It is an enantiomer of a (R,R,R)-alpha-tocopherol. (-)-alpha-Tocopherol is a natural product found in Calea jamaicensis, Euglena gracilis, and other organisms with data available. A generic descriptor for all TOCOPHEROLS and TOCOTRIENOLS that exhibit ALPHA-TOCOPHEROL activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS.

5-tricosenylresorcinol is a member of the class of compounds known as resorcinols. Resorcinols are compounds containing a resorcinol moiety, which is a benzene ring bearing two hydroxyl groups at positions 1 and 3. 5-tricosenylresorcinol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 5-tricosenylresorcinol can be found in breakfast cereal and common wheat, which makes 5-tricosenylresorcinol a potential biomarker for the consumption of these food products.

5-stigmastene-3beta,7alpha-diol belongs to stigmastanes and derivatives class of compounds. Those are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. 5-stigmastene-3beta,7alpha-diol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 5-stigmastene-3beta,7alpha-diol can be found in pineapple, which makes 5-stigmastene-3beta,7alpha-diol a potential biomarker for the consumption of this food product.

(22alpha)-hydroxy-sitosterol belongs to stigmastanes and derivatives class of compounds. Those are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24 (22alpha)-hydroxy-sitosterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). (22alpha)-hydroxy-sitosterol can be found in a number of food items such as cottonseed, oil-seed camellia, cloves, and dill, which makes (22alpha)-hydroxy-sitosterol a potential biomarker for the consumption of these food products.

4beta-hydroxymethyl-4alpha-methyl-5alpha-cholest-7-en-3beta-ol, also known as 4a-methyl-4b-hydroxymethyl-5a-cholest-7-en-3b-ol, belongs to cholesterols and derivatives class of compounds. Those are compounds containing a 3-hydroxylated cholestane core. Thus, 4beta-hydroxymethyl-4alpha-methyl-5alpha-cholest-7-en-3beta-ol is considered to be a sterol lipid molecule. 4beta-hydroxymethyl-4alpha-methyl-5alpha-cholest-7-en-3beta-ol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 4beta-hydroxymethyl-4alpha-methyl-5alpha-cholest-7-en-3beta-ol can be found in a number of food items such as broad bean, summer savory, hyssop, and alpine sweetvetch, which makes 4beta-hydroxymethyl-4alpha-methyl-5alpha-cholest-7-en-3beta-ol a potential biomarker for the consumption of these food products. 4beta-hydroxymethyl-4alpha-methyl-5alpha-cholest-7-en-3beta-ol may be a unique S.cerevisiae (yeast) metabolite.
