ubiquinone-1

Ubiquinone-1 (UQ-1) is an intermediate in the biosynthesis of coenzyme Q, an essential coenzyme in the body's redox reactions, involved in multiple oxidation-reduction processes.

Coenzyme Q6 (Ubiquinone 30), an isoprenylated benzoquinone lipid, plays a pivotal role in respiratory electron transport and acts as a lipid antioxidant. Besides, it possesses antioxidant properties that inhibit the generation of free radicals and prevent oxidative damage [1].

Coenzyme Q8 (Ubiquinone 8) is an isoprenoid quinone isolated from the plasma membrane of wild-type or long-lived qm30 and qm51 clk-1 mutant strains of Cryptomeria cepacia that mediates electron transfer in the aerobic respiratory chain and reduces oxidative stress.
