Common Name | 2-Octaprenyl-3-methyl-6-methoxy-1,4-benzoquinol |
---|
Description | 2-octaprenyl-3-methyl-6-methoxy-1,4-benzoquinol (DMQH2) is an intermediate in coenzyme Q biosynthesis. It is produced by gut microbes. In microbes, the starting compound, 4-hydroxybenzoate, undergoes a prenylation, a decarboxylation and three hydroxylations alternating with three methylation reactions, resulting in the formation of coenzyme Q. In the final step, DMQH2 is converted from 2-octaprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) with the help of Methyltransferase. Coenzyme Q (ubiquinone or Q) is a redox active lipid containing a long polyprenyl tail attached to a fully substituted benzoquinone ring. The number (n) of isoprene units in the polyprenyl tail (Qn) is distinct in different organisms; humans produce Q10, Caenorhabditis elegans Q9, Escherichia coli Q8, and Saccharomyces cerevisiae Q6. |
