Citrulline/malate promotes aerobic energy production in human exercising muscle.
BACKGROUND Previous studies have shown an antiasthenic effect of citrulline/malate (CM) but the mechanism of action at the muscular level remains unknown. OBJECTIVE To investigate the effects of CM supplementation on muscle energetics. METHODS Eighteen men complaining of fatigue but with no documented disease were included in the study. A rest-exercise (finger flexions)-recovery protocol wa...
متن کاملAerobic anoxygenic phototrophic bacteria.
The aerobic anoxygenic phototrophic bacteria are a relatively recently discovered bacterial group. Although taxonomically and phylogenetically heterogeneous, these bacteria share the following distinguishing features: the presence of bacteriochlorophyll a incorporated into reaction center and light-harvesting complexes, low levels of the photosynthetic unit in cells, an abundance of carotenoids...
متن کاملRelative contributions of archaea and bacteria to aerobic ammonia oxidation in the environment.
Traditionally, organisms responsible for major biogeochemical cycling processes have been determined by physiological characterization of environmental isolates in laboratory culture. Molecular techniques have, however, confirmed the widespread occurrence of abundant bacterial and archaeal groups with no cultivated representative, making it difficult to determine their ecosystem function. Until...
متن کاملMalate Dehydrogenase and NAD Malic Enzyme in the Oxidation of Malate by Sweet Potato Mitochondria.
Over a range of concentrations from less than 0.1 mm to more than 70 mm, sweet potato root mitochondria display a bimodal substrate saturation isotherm for malate. The high affinity portion of the isotherm has an apparent Km for malate of 0.85 mm and fits a rectangular hyperbolic function. The low affinity portion of the isotherm is sigmoid in character and gives an apparent S(0.5) of 40.6 mm a...
متن کاملNADH, Succinate and Malate Oxidation in Corn Mitochondrial
state 4 and state 3 conditions was studied with corn shoot mitochondria. Comparisons were made.' usin malate and succinate as'-substrates. The inhibitors, rotenone, amvtal. antimycin A andcyanide, inhibited oxidation of NADH in state 3 but rotenone and amytal did not inhibit oxidation in state 4. The inhibition by antimycin A was partially overcome by the presence of cytochrome c. The results i...
