ADVANCED USE OF COENZYME Q10 IN PATIENTS WITH CARDIOVASCULAR DISEASES

open access: yesЕвразийский Кардиологический Журнал, 2013
This report examines interest in compounds that normally prevent the toxic effects of ROS -antioxidants, namely reduced ubiquinone, which is only lipid soluble antioxidant synthesized in cells of animals and humans, and continuously recovered from ...

Programming Saposin-Mediated Compensatory Metabolic Sinks for Enhanced Ubiquinone Production

open access: yes, 2016
Microbial synthesis of ubiquinone by fermentation processes has been emerging in recent years. However, as ubiquinone is a primary metabolite that is tightly regulated by the host central metabolism, tweaking the individual pathway components could only ...

Investigation of conserved amino acids in the PSST and TYKY subunits of complex I from Yarrowia lipolytica

open access: yes, 2005
Proton-translocating NADH:ubiquinone oxidoreductase (complex I) transports two electrons from NADH to membranal ubiquinone: in this process protons are translocated across the membrane, producing 40% of the total proton gradient between matrix side and ...

The Modulation of Ubiquinone, a Lipid Antioxidant, on Neuronal Voltage-Gated Sodium Current

open access: yes, 2022
Ubiquinone, composed of a 1,4-benzoquinone and naturally produced in the body, actively participates in the mitochondrial redox reaction and functions as an endogenous lipid antioxidant, protecting against peroxidation in the pituitary-dependent hormonal

Identification of Ubiquinones in Honey: A New View on Their Potential Contribution to Honey’s Antioxidant State

open access: yesMolecules, 2018
Honey is composed of macromolecules arranged into multicomponent colloidal particles dispersed in a supersaturated sugar solution. The core part of colloidal particles in honey is made up of high-molecular weight protein-polyphenol complexes. We designed

The alleged absence of ubiquinone from elasmobranchs

open access: yes, 1966
It has recently been suggested (Diplock & Haslewood, 1964) that certain lower vertebrates such as elasmobranchs and crocodylians are lacking in ubiquinone.

Hybrid ubiquinone: novel inhibitor of mitochondrial complex I

open access: yes, 2002
We synthesized novel ubiquinone analogs by hybridizing the natural ubiquinone ring (2,3-dimethoxy-5-methyl-1,4-benzoquinone) and hydrophobic phenoxybenzamide unit, and named them hybrid ubiquinones (HUs).

The regulation of the biosynthesis of ubiquinone in the rat

open access: yes, 1975
The urinary excretion of p-hydroxybenzoate was not altered by ubiquinone feeding, but, although decreased considerably, was not eliminated in protein deficiency.

The electron transfer flavoprotein: Ubiquinone oxidoreductases

open access: yes, 2010
Electron transfer flavoprotein:ubiqionone oxidoreductase (ETF-QO) is a component of the mitochondrial respiratory chain that together with electron transfer flavoprotein (ETF) forms a short pathway that transfers electrons from 11 different mitochondrial

Fluidizing effect of endogenous ubiquinone in bovine heart mitochondrial membranes

open access: yes, 1984
Extraction of endogenous ubiquinone from lyophilized beef heart mitochondria results in increases of both the order parameter of the spin label 5-NS and of the rotational correlation time of 16-NS; reconstitution with the pentane extract results in ...
