應用

Coenzyme Q4 (CoQ4) is a 4 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 where they perform multiple functions such as electron and proton transport. The most well studied CoQ compound is CoQ10. CoQ4 is frequently used in comparison studies on the effect of isoprenyl chain length on CoQ functions or distribution.

生化/生理作用

Increases the fluorescence polarization of perylene incorporated into ubiquinone-depleted mitochondrial and bilayer vesicles prepared from mitochondrial phospholipids

Adriamycin inhibits the succinoxidase system and the NADH-oxidase system. Both of the intact mitocondrial enzymes and the pentane-extracted preparations are inhibited. The inhibition can be prevented by a molar ratio of coenzyme to adriamycin of 3:1 for coenzyme Q10 (ubiquinone)
