(1) These include alkylsulfonates, alkylsulfates and their derivatives, benzenesulfonate, oxohalogenides, hypophosphate, hexafluorophosphate, and pyruvate.
Hypophosphite
Definition:
(n.) A salt of hypophosphorous acid.
Example Sentences:
(1) Furthermore, it is insufficient to fully account for the transmembrane chemical shift differences observed for dimethyl methylphosphonate and hypophosphite.
(2) The formate analogue hypophosphite has been characterized as a specific kcat inhibitor of pyruvate formate-lyase which destroys the enzyme radical.
(3) Adaptation to hypophosphite, however, led simultaneously to phosphite adaptation, so that these cells can utilize both P-compounds as a substitute for phosphate.
(4) The difference in the magnetic susceptibility of the intra- and extracellular compartments contributes to the observed separation of the intra- and extracellular resonances of dimethyl methylphosphonate and hypophosphite.
(5) Trimethyl phosphate, dimethyl methylphosphonate, diethyl methylphosphonate, trimethylphosphine oxide, and the hypophosphite, phenylphosphinate, and diphenylphosphinate ions all contain the phosphoryl functional group.
(6) The observed adaptation pattern, reflected by the alterations of phosphatase activity, was qualitatively equal with PO3-3 and PO3-2, but quantitatively different, because the response to hypophosphite gave much higher values than the increase obtained with phosphite.
(7) Zaprionus paravittiger fed with an antioxidant (sodium hypophosphite, 1 X 10(3) microM) supplemented diet exhibited adaptive compensatory responses in catalase activity (quantitative as well as qualitative).
(8) The intracellular NMR-determined viscosities from red cells, ranging in volume from 65.5 to 100.1 fl, varied from 2.10 to 2.67 mPa s. This is consistent with the translational diffusion coefficients of the hypophosphite ion altering by only 20%, whereas the values determined from bulk viscosity measurements conducted on lysates of these cells are consistent with a 230% change.
(9) It was also inhibited by hypophosphite, an inhibition that was reversed by formate.
(10) Formaldehyde, hypophosphite, nitrate, and bicarbonate all inhibited the oxidation of formate.
(11) Sodium hypophosphite (1 x 10(3) microM) supplementation in the diet of Zaprionus paravittiger resulted in adaptive responses in the quantitative as well as qualitative activity of peroxidase.
(12) These compounds include phosphate, phosphite, hypophosphite, fluorophosphate, thiophosphate, methylphosphonate, and dimethylphosphinate.
(13) On the basis of our findings, the previous work of Knappe and co-workers, the likelihood that hypophosphite is a formate analogue, the known susceptibility of both hypophosphite and formate to homolysis, and a chemical precedent for homolytic cleavage of pyruvate, we offer a preliminary mechanistic proposal for the lyase reaction.
(14) Hypophosphorus acid has a single pKa of 1.1 and at physiological pH values it is therefore present almost entirely as the univalent hypophosphite ion.
(15) When Escherichia coli cells were grown in media containing either phosphite or hypophosphite as the sole source of phosphorus, the responded to this situation primarily in the same way as phosphate-limited cultures: The activity of alkaline phosphatase increased drastically, which under natural conditions would enable the cells to compensate for the shortage of phosphate.
(16) We report here that the inactivation of both the free and acetylated forms of the lyase is subject to a primary kinetic isotope effect using [2H2]hypophosphite.
(17) capable of utilizing phosphite and hypophosphite under anaerobic conditions was isolated from Cape Canerval soil samples.
(18) This enzyme is inhibited by low concentrations of potassium cyanide, copper sulphate and hypophosphite.
(19) Formaldehyde resistance can be drastically lowered down to 4 mM by blocking the formate dehydrogenase by means of hypophosphite.
(20) From a single 31P NMR spectrum it was possible to determine the relative amounts of hypophosphite in the intra- and extracellular compartments and thereby estimate the corresponding concentrations.
