Specific and rapid analysis of ubiquinones using Craven's reaction and HPLC with postcolumn derivatization

Journal of Lipid Research, 2007
A new method for the analysis of ubiquinones in various samples was developed using an HPLC system with postcolumn derivatization. Craven's reaction, a specific color reaction for the analysis of ubiquinones, was used in the system.

Novel Cationic Prodrug of Ubiquinol-10 Enhances Intestinal Absorption via Efficient Formation of Nanosized Mixed-Micelles with Bile Acid Anions

Molecules, 2020
The aim of this study was to develop a prodrug of ubiquinol-10 (UqH-10), the active form of ubiquinone-10 (Uq-10), for oral delivery. Bioavailability of UqH-10 is hampered by its high susceptibility to oxidation and water-insolubility.

Ubiquinone binding, ubiquinone exclusion, and detailed cofactor conformation in a mutant bacterial reaction center

, 2000
The X-ray crystal structure of a Rhodobacter sphaeroides reaction center with the mutation Ala M260 to Trp (AM260W) has been determined. Diffraction data were collected that were 97.6% complete between 30.0 and 2.1 Angstrom resolution.

Cerebellar defects in Pdss2 conditional knockout mice during embryonic development and in adulthood

Neurobiology of Disease, 2012
PDSS2 is a gene that encodes one of the two subunits of trans-prenyl diphosphate synthase that is essential for ubiquinone biosynthesis. It is known that mutations in PDSS2 can cause primary ubiquinone deficiency in humans and a similar disease in mice ...

Ferulenol specifically inhibits succinate ubiquinone reductase at the level of the ubiquinone cycle

, 2007
The natural compound ferulenol, a sesquiterpene prenylated coumarin derivative, was purified from Ferula vesceritensis and its mitochondrial effects were studied. Ferulenol caused inhibition of oxidative phoshorylation.

Pyridoxal phosphate-induced dissociation of the succinate : ubiquinone reductase

, 1985
Treatment of the soluble ubiquinone-deficient succinate: ubiquinone reductase with pyridoxal phosphate results in the inhibition of the carboxin-sensitive ubiquinone-reductase activity of the enzyme.

The isoprenyl chain length of coenzyme Q mediates the nutritional resistance of fungi to amoeba predation

mBio
Amoebae are environmental predators feeding on bacteria, fungi, and other eukaryotic microbes. Predatory interactions alter microbial communities and impose selective pressure toward phagocytic resistance or escape which may, in turn, foster virulence ...

Biosynthesis of ubiquinone and ubichromenol in vitamin A-deficient rats

, 1966
1. The concentrations of ubiquinone and ubichromenol increased in the livers, but not in the intestines and kidneys, of rats maintained on a diet deficient in vitamin 2. After short time intervals (e.g.
