DescriptionUbiquinone-8, also known as coenzyme Q8 or COQ8, 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, ubiquinone-8 is considered to be a quinone. Ubiquinone-8 exists in all living organisms, ranging from bacteria to humans. Ubiquinone-40 is found in Allochromatium vinosum, Chromatium and Hevea brasiliensis. Ubiquinone-40 was first documented in 1964 (PMID: 14240125). Based on a literature review a small amount of articles have been published on ubiquinone-8 (PMID: 34369861) (PMID: 34343063) (PMID: 34319259) (PMID: 34296988).
