Studies on Uric Acid and Related Compounds
The systematic study of the substrate specificity of mammalian xanthine oxidase has indicated a common mechanism by which various purines may be dehydrogenated (1). The results obtained also made it clear why methylated xanthines, with the exception of 1-methylxanthine (2), cannot be oxidized by xanthine oxidase to the corresponding substituted uric acids (3, 4). Therefore, another source had t...
متن کاملSystematic studies of tannin–formaldehyde aerogels: preparation and properties
Gelation of tannin-formaldehyde (TF) solutions was systematically investigated by changing pH and concentration of TF resin in water. In this way we constructed the TF phase diagram, from which chemical hydrogels could be described, and also synthesized thermoreversible tannin-based hydrogels. Conditions of non-gelation were also determined. Hydrogels were dried in supercritical CO2, leading to...
متن کاملInoculation of tannin-degrading bacteria into novel hosts increases performance on tannin-rich diets.
It has been hypothesized that herbivores host tannin-degrading bacteria (TDB) to overcome the toxic challenges posed by plant tannins. While TDB have been isolated from the guts of numerous mammals, their functional significance to their hosts has never been explicitly tested. We introduced TDB into lab rats, which do not host TDB, and measured host performance on tannin-rich diets. We first is...
متن کاملStudies on GC/MS Spectroscopic Analysis of some Bioactive Antimicrobial Compounds from Cinnamomum zeylanicum
Background: Infectious diarrhoea is an emergent problem in both developing and developed countries for high rates of mortality in infants. In recent years, drug resistance to microbial pathogens has been commonly reported from all over the world. Medicinal plants represent a rich source of antimicrobial agents. Plants are used medicinally in different countries especially in India and are a sou...
متن کاملA Review on Biohydrogenation and Effects of Tannin on It
The process called biohydrogenation occurs mainly in ruminant animals and during it, unsaturated fatty acids, and particularly poly-unsaturated ones (linoleic and linolenic) coverts to a saturated form of stearic acid. For many years, the beneficial effects of biohydrogenation intermediate fatty acids like cis-9 trans-11 linoleic acid, the main natural isomer of conjugated linoleic acids (CLA),...
