Hexose monophosphate shunt in rat lens: stimulation by vitamin C.
The metabolism of glucose through the hexose monophosphate (HMP) shunt has been studied in rat lens in vitro, in the absence and presence of ascorbic and dehydroascorbic acids. Both forms of the vitamin stimulated the utilization of glucose through the HMP shunt, the stimulatory effect of dehydroascorbate being substantially greater than that of ascorbate. The stimulatory effect of ascorbate, a...
متن کاملStimulation of leukocyte hexose monophosphate shunt activity by ascorbic Acid.
Ascorbic acid in vitro markedly stimulates the hexose monophosphate shunt in normal human neutrophils, rabbit alveolar macrophages, and in neutrophils from a patient with chronic granulomatous disease.
متن کاملOzone Inhibition of Photosynthesis in Chlorella sorokiniana.
Exposure of Chlorella sorokiniana (07-11-05) to ozone inhibits photosynthesis. In this study, the effects of ozone on O(2) evolution and fluorescence yields are used to characterize this inhibition. At an ozone dose of about 3 micromoles delivered to 2 x 10(9) cells, the photosynthetic rate of the cells is inhibited 50%, as indicated by a decrease in bicarbonate-stimulated O(2) evolution (contr...
متن کاملMechanisms of methylene blue stimulation of the hexose monophosphate shunt in erythrocytes.
The response of the hexose monophosphate shunt in erythrocytes was studied with the ionization chamber-electrometer apparatus to measure continuously 14CO2 derived from 14C-labeled substrates. The effect of methylene blue at high (0.1 mM) and low (1 muM) concentrations was evaluated under different gas mixtures; air, carbon monoxide, and 6% carbon monoxide in air. The latter gas mixture results...
متن کاملStimulation of the hexose monophosphate shunt in human neutrophils by ascorbic acid: mechanism of action.
The addition of either ascorbic acid or dehydroascorbic acid to a suspension of polymorphonuclear leukocytes caused a dramatic increase in the resting hexose monophosphate shunt activity. A sequence of reactions involving dehydroascorbate, reduced glutathione, and reduced nicotinamide adenine dinucleotide phosphate is described to explain this stimulation. This sequence could provide an alterna...
