“…T h e solubilities of carbon dioxide, air, oxygen, nitrogen, and hydrogen in corn oil, in both unhydrogenated and hydrogenated lard, and in cottonseed oil have been measured at various temperatures b y several investigators (1)(2)(3). They found that all the gases, with the exception of carbon dioxide, are increasingly soluble in the fat as the temperature rises.…”

“…H 2 is a hydrophobic, non-polar molecule and has a lower solubility in water (0•8 mmol/l at 20°C) than oxygen (1•34 mmol/l at 20°C), a similar hydrophobic, non-polar molecule. Being more soluble in oil and organic solvents than in water (8) , H 2 is likely localised more frequently in biological membranes and adipose tissue. For example, in our previous study, we found that, in rats that were fed a diet of non-digestible saccharides, H 2 was produced in the colon and its concentration was greater in the adipose tissue than in other tissues.…”

Hydrogen produced in rat colon improves in vivo reduction–oxidation balance due to induced regeneration of α-tocopherol

We investigated whether non-digestible saccharide fermentation-derived hydrogen molecules (H2) in rat colon could improve the in vivo reduction–oxidation (redox) balance via regeneration of α-tocopherol, by assessing their effect on hydroxyl radicals, the α-tocopherol concentration and the redox balance. In Expt 1, a Fenton reaction with phenylalanine (0 or 1·37 mmol/l of H2) was conducted. In Expt 2, rats received intraperitoneally maize oil containing phorone (400 mg/kg) 7 d after drinking ad libitum water containing 0 or 4 % fructo-oligosaccharides (FOS) (groups CP and FP, respectively). In Expt 3, rats unable to synthesise ascorbic acid drank ad libitum for 14 d water with 240 mg ascorbic acid/l (group AC), 20 mg of ascorbic acid/l (group DC) or 20 mg of ascorbic acid/l and 4 % FOS (group DCF). In the Fenton reaction, H2 reduced tyrosine produced from phenylalanine to 72 % when platinum was added and to 92 % when platinum was excluded. In Expt 2, liver glutathione was depleted by administration of phorone to rats. However, compared with CP, no change in the m-tyrosine concentration in the liver of FP was detected. In Expt 3, net H2 excretion was higher in DCF than in the other rats after 3 d of the experiment. Furthermore, the concentrations of H2 and α-tocopherol and the redox glutathione ratio in perirenal adipose tissue of rats were significantly higher in DCF than in DC. To summarise, in rat colon, fermentation-derived H2 further shifted the redox balance towards a more reducing status in perirenal adipose tissue through increased regeneration of α-tocopherol.
