Hydrogen sulfide and the metabolic syndrome
Expert Review of Clinical Pharmacology, 2011The metabolic syndrome is a group of abnormalities including obesity, high blood pressure, hyperinsulinemia, high blood glucose levels and hyperlipidemia that together greatly increase the risk of developing cardiovascular disease and Type 2 diabetes.

Hydrogen metabolism by filamentous cyanobacteria
Archives of Biochemistry and Biophysics, 1980Abstract Apparent discrepancies in the literature concerning the amounts of H 2 produced by strains of Anabaena cylindrica are explained. These are not due to differences in strains used by different workers nor to differences in growth conditions, but rather appear to be due to the fact that cultures show an increasing dependence with age on CO 2

Anaerobic Formate and Hydrogen Metabolism
EcoSal Plus, 2004During fermentative growth, Escherichia coli degrades carbohydrates via the glycolytic route into two pyruvate molecules. Pyruvate can be reduced to lactate or nonoxidatively cleaved by pyruvate formate lyase into acetyl-coenzyme A (acetyl-CoA) and formate.

Anaerobic Formate and Hydrogen Metabolism
EcoSal Plus, 2016Numerous recent developments in the biochemistry, molecular biology, and physiology of formate and H 2 metabolism and of the [NiFe]-hydrogenase (Hyd) cofactor biosynthetic machinery are highlighted. Formate export and import by the aquaporin-like pentameric formate channel FocA is governed by interaction with ...

Analysis of Trace Hydrogen Metabolism
2005H2 maintains an important role in bacterial metabolism in anaerobic environments. The ability to measure and analyze H2 concentrations in biological systems is often useful for determining the physiological state of the microbiota. Methods for precisely analyzing H2 in bacterial cultures and environmental samples are now available.

Genetic control of hydrogen metabolism in cyanobacteria
Russian Journal of Genetics, 2006The development of methods for the use of phototrophic cyanobacteria as producers of molecular hydrogen via bioconversion of solar energy is a promising filed of hydrogen energetics. Artificial optimization of hydrogen formation and release is based on studying the genetic control of hydrogen metabolism and the use of genetic approaches for obtaining ...

Lactoperoxidase and Hydrogen Peroxide Metabolism in the Airway
American Journal of Respiratory and Critical Care Medicine, 2002Abstract Hydrogen peroxide (H2O2) is known to play an important role in airway homeostasis. For this reason its levels and thus its synthesis and consumption are important mechanisms for controlling airway functions. We have identified the major macromolecular consumer of H2O2 in sheep airway secretions to be lactoperoxidase (LPO), a ...

Hydrogen metabolism in blue-green algae
Biochimie, 1978This manuscript reviews the literature on hydrogen metabolism in blue-green algae and reports some new data from this laboratory. H2-formation by intact cells is found to be catalyzed exclusively by nitrogenase. Its rate appears to be variable from strain to strain used byt is--in our hands--very small.

The Metabolic Fate of Mitochondrial Hydrogen Peroxide
European Journal of Biochemistry, 1980Mitochondrial H2O2formation is not in equilibrium with defence mechanisms that counteract an accumulation of H2, in rat‐heart cell.A model for the accumulation kinetics is proposed which is consistent with the data presented.Four different pathways of H2O2metabolism are described in rat‐heart mitochondria.
