| Common Name | 3-Demethylubiquinone-9 |
|---|
| Description | 3-Demethylubiquinone-9 belongs to the class of organic compounds known as ubiquinones. These are coenzyme Q derivatives containing a 5, 6-dimethoxy-3-methyl(1,4-benzoquinone) moiety to which an isoprenyl group is attached at ring position 2(or 6). Thus, 3-demethylubiquinone-9 is considered to be a quinone lipid molecule. 3-Demethylubiquinone-9 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. |
