Chemical Properties
Bright Yellow Solid
Uses
Coenzyme Q
9 has been used to investigate its interference in the detection of coenzyme Q
10 (CoQ
10) by fluorescent spectrophotometer (FS-ECA). It has also been used as an analyte in chromatographic analysis of different biological samples that correspond to different genetic conditions.

Uses
Antibacterial and antioxidant for preventing and treating cancer.
Definition
ChEBI: Ubiquinone-9 is a member of ubiquinones. It has a role as an antioxidant and a human metabolite.
General Description
Coenzyme Q9 (Ubiquinone-9; Ubi-9) is a 9 isoprenyl group member of a family of ubiquinones that share a quinine chemical group but differ in the number of isoprenyl chemical subunits in their tail. The CoQ compounds are lipid soluble components of cell membranes.
Biochem/physiol Actions
The coenzyme Q (CoQ) can perform multiple functions such as electron and proton transport. CoQ9 performs similar functions to CoQ10 as the native CoQ in Caenorhabditis elegans. CoQ9 as well as other CoQ molecules may have an impact on cell life-span and these molecules are seeing increase usage in such studies.
Purification Methods
The yellow crystals are purified by recrystallisation from pet ether and by chromatography on SiO2 plates and eluted with Et2O/hexane. The purity can be checked by HPLC (silica column using 7% Et2O/hexane). It has max 270nm ( 14,850) in pet ether. [NMR and MS: Naruta J Org Chem 45 4097 1980, Le et al.
