gamma-Tocopherol, the major form of dietary vitamin E, is absorbed in the intestine and is secreted in chylomicrons, which are then transferred to liver lysosomes. Most gamma-tocopherol is transferred to liver microsomes and is catabolized by cytochrome p450. Due to the hydrophobicity of gamma-tocopherol, a binding and transfer protein is plausible, but none have yet been isolated and character...

Coenzyme Q10 (CoQ10) is a key component of the mitochondrial electron transfer chain and is one of the most important cellular antioxidants. We previously reported that glycoprotein saposin B (SapB) binds CoQ10 in human cells. To elucidate the physiological role of SapB and its precursor, prosaposin (Psap), we prepared stable transfectants of HepG2 that overexpress wild-type human Psap (Wt-Tf)....

Todays, parallel to growing in acceptance of functional products, various additives are used to improve the characteristics of functional food products. The coenzyme Q10 is an essential component for energy conversion and production of adenosine triphosphate (ATP) in the membranes of all body cells and organelles, especially the inner mitochondrial membrane is found. Coenzyme Q10 plays a vital ...

The possibility of preparation of hydrogenated phosphatidylcholine (HPC) liposome precursors (LP) using supercritical anti-solvent technology (SAS) was evaluated. Vitamin D (VD) and coenzyme Q10 (CoQ10) were chosen as the model drugs, and HPC was used as the wall material. The influences of operation conditions (pressures, concentrations and etc.) on the HPC were studied. The structure of the L...

In 2001, we described six patients with cerebellar ataxia and severe deficiency of coenzyme Q10 (CoQ10, ubiquinone) in skeletal muscle [1]. Within one year, we described 13 additional patients [2]; therefore, we suspected this was not a very rare syndrome. Twelve years after our original report, cerebellar ataxia and atrophy has emerged as the most common clinical presentation of CoQ10 deficien...

CoQ10 was discovered by Dr. Frederick L. Crane at the University of Wisconsin in the late 1950s during his research on the biochemistry of the mitochondrial electron transport chain, also known as the respiratory chain. The pure substance isolated from beef heart mitochondria was sent to Dr. Karl Folkers at the pharmaceutical company Merck for identification and elucidation of its structure. It...

introduction: indomethacin increases generation of mitochondrial reactive oxygen species (ros) which have a crucial role in the indomethacin-induced gastric ulcer. coenzyme q10 has an antioxidant activity on mitochondria and cell membranes and protects lipids from oxidation and is essential for stabilizing biological membranes. superoxide dismutase (sod) acts as one of the defense mechanisms ag...

conclusions coq10 abolished neuropathic pain in cci rats. prevention of cell loss might be attributed to the analgesic effect of coq10. hence, it might be used as a therapeutic intervention for neuropathic pain. background oxidative stress contributes to neuropathic pain. coenzyme q10 (coq10) is used for the treatment of neurodegenerative diseases. however, there is no report regarding the ther...

Background: Alzheimer’s disease (AD) is a neurodegenerative disorder greatly influenced by oxidative stress and mitochondrial dysfunction which may lead to deposition of β-amyloid (Aβ) peptides. Protein malnutrition increases oxidative damage in cortex, hippocampus and cerebellum. Epigallocatechin-3-gallate (EGCG) has health-promoting effects in CNS, while Coenzyme Q10 (CoQ10) is intracellular ...
