Coenzyme Q (CoQ) is an essential player in the respiratory electron transport chain and is the only lipid-soluble antioxidant synthesized endogenously in mammalian and yeast cells. In humans, genetic mutations, pathologies, certain medical treatments, and aging, result in CoQ deficiencies...

The rate constants (ks) of 1O2 scavenging for alpha-tocopherol (alpha-Toc) and beta-carotene (beta-Car) were measured in liposome membranes, and compared with those in EtOH solution. 1O2 was site-specifically generated by photoirradiation using two photosensitizers, water-soluble Rose bengal (RB) and lipid-soluble...

Aqueous dispersions of 12-(1-pyrene)-dodecanoic acid (P12), a medium-chain fatty acid to which the fluorescent probe pyrene has been covalently linked, shows a considerable increase in fluorescence when the probe is introduced into a hydrophobic environment. This enables the uptake of...

Because it has been reported that hypoxia in rats may promote lipid peroxidation and other free radical reactions that could modify membrane lipids and proteins, the effect of acute hypobaric hypoxia on human erythrocyte membranes was investigated. 12-(1-Pyrene)dodecanoic acid fluorescent...
