2,3-DIMETHOXY-5-METHYL-6-[ALL TRANS]FARNESYLFARNESYL-1,4-BENZOQUINONE

Uses

CoQ6 has been used:

• as an internal standard for the liquid-chromatography mass-spectrometry for the quantification of CoQ6
• to determine its effect on peroxisome proliferator-activated receptor (PPAR)
• in reversed-phase high pressure liquid chromatography to quantify yeast quinones

Definition

ChEBI: A ubiquinone compound having a (2E,6E,10E,14E,18E)-3,7,11,15,19,23-hexamethyltetracosa-2,6,10,14,18,22-hexaen-1-yl substituent at position 2.

General Description

Coenzyme Q6 (CoQ6) is also known as ubiquinone-30 in Saccharomyces cerevisiae. It is a flavoprotein that utilizes flavin adenine dinucleotide (FAD) as a co-factor for the synthesis of coenzyme Q. It is composed of three conserved regions- a FAD/ nicotinamide adenine dinucleotide (NAD) + hydrogen (H) (NADH) binding motif, an adenine di phosphate (ADP) binding motif and a consensus sequence, that binds to the ribityl moiety of FAD.

Biochem/physiol Actions

Coenzyme Q6 (CoQ6) in the plasma membrane of Saccharomyces cerevisiae is involved in the ascorbate stabilization at the plasma membrane.
