Description | 4alpha-carboxy-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 oxidation of 4alpha-formyl-4beta-methyl-5alpha-cholesta-8-en-3beta-ol. It is also a substrate for NAD(P)-dependent steroid dehydrogenase (H105E3) and can be generated from the enzymatic carboxylation of 4alpha-methyl-5alpha-cholesta-8-en-3-one. 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. |
