Effect of Coenzyme Q₁₀ Incorporation on the Characteristics of Nanoliposomes

The Journal of Physical Chemistry B, 2007
Coenzyme Q(10) (CoQ(10)) is incorporated in nanoliposomes composed of egg yolk phospholipid, cholesterol, and Tween 80. Atomic force microscopy, performed to characterize vesicle surface topology, shows some visible influence of CoQ(10) on the nanoliposomal structure.

Use of coenzyme Q-10 to improve the pregnancy rate in sheep

Animal Reproduction Science
One of the factors responsible for less pregnancy rates is the use of frozen semen in sheep due to the oxidative stress created by the process. The aim of this experiment was to test the effects of adding coenzyme Q-10 (CoQ10) to the seminal extender on sperm quality and the pregnancy rate of sheep.

A Short, Highly Efficient Synthesis of Coenzyme Q₁₀

Journal of the American Chemical Society, 2002
The most efficient synthesis reported to date of ubiquinone (CoQ10) is described. A sequence consisting of six operations is involved which leads to crystalline material in an overall yield of >64%.

Coenzyme Q₁₀, endothelial function, and cardiovascular disease

BioFactors, 2011
AbstractSince the time a precise role of coenzyme Q10 (CoQ10) in myocardial bioenergetics was established, the involvement of CoQ in the pathophysiology of heart failure was hypothesized. This provided the rationale for numerous clinical trials of CoQ10 as adjunctive treatment for heart failure.

Pediatric reference intervals for muscle coenzyme Q₁₀

Biomarkers, 2012
Coenzyme Q(10) (CoQ(10)) is present in humans in both the reduced (ubiquinol, CoQ(10)H(2)) and oxidized (ubiquinone, CoQ(10)) forms. CoQ(10) is an essential cofactor in mitochondrial oxidative phosphorylation, and is necessary for ATP production. Total, reduced and oxidized CoQ(10) levels in skeletal muscle of 148 children were determined by HPLC ...

The uptake and distribution of coenzyme Q(10)

Mitochondrion, 2007
This review describes recent advances in our understanding of the uptake and distribution of coenzyme Q10 (CoQ10) in cells, animals, and humans. These advances have provided evidence of important pharmacokinetic factors, such as non-linear absorption and enterohepatic recirculation, and may facilitate the development of new CoQ10 formulations.

Coenzyme Q-10 in Human Health: Supporting Evidence?

Southern Medical Journal, 2016
Coenzyme Q-10 (CoQ10) is a widely used alternative medication or dietary supplement and one of its roles is as an antioxidant. It naturally functions as a coenzyme and component of oxidative phosphorylation in mitochondria. Decreased levels have been demonstrated in diseased myocardium and in Parkinson disease.

Koencim Q 10: Coenzyme Q 10:

2008
Koencim Q 10 (KoQ), poznan tudi kot ubikinon, je po načinu delovanja podoben vitaminom. Pomemben je pri sintezi adenozin trifosfata (ATP) v mitohondrijih in je učinkovit antioksidant. Pomanjkanje KoQ v telesu je posledica premajhnega vnosa s hrano, motnje v biosintezi ali pa v povečanih potrebah organizma.

Synthetic Studies on Coenzyme Q₁₀

Helvetica Chimica Acta, 2005
AbstractA practical, highly stereoselective ten‐step synthesis of coenzyme Q10 (1) has been accomplished (overall yield ca. 28%), starting from commercially available 2,3‐dimethoxy‐5‐methylbenzoquinone (Scheme). The introduction of the first side‐chain isoprenyl group with (E)‐configuration (compound 6) was realized by means of a coupling reaction of ...

[Coenzyme Q 10 in psychiatry].

Acta psiquiatrica y psicologica de America latina, 1995
The incidence of coenzyme Q 10 and its alterations in psychiatrical pathology is studied. A screening of a randomly selected 113-patient sample showed a high percentage of deficiencies: When taken care of, an improvement in patients' clinical pictures, with no secondary complaint could be observed.
