In the title compound, [Cd(HCOO)(2)(C(10)H(8)N(2))](n), the Cd(II) ion, located on a position with 2.22 site symmetry, is surrounded by two 4,4'-bipyridine ligands and four formate ligands in a distorted octahedral CdN(2)O(4) coordination. The 4,4'-bipyridine ligands bridge the metal ions, forming one-dimensional chains along different directions, which are further connected by formate ligands ...

Phagocytosis-induced formate and glucose C-1 oxidation by the polymorphonuclear leukocytes of a patient with hereditary myeloperoxidase deficiency was considerably greater than normal. The addition of catalase to the leukocyte suspension was required for optimum formate oxidation. Azide and cyanide increased glucose C-1 oxidation by normal leukocytes but had little or no effect on myeloperoxida...

Dimethylammonium magnesium formate, [(CH$_3$)$_2$NH$_2$][Mg(HCOO)$_3$] or DMAMgF, is a model to study high temperature hybrid perovskite-like dielectrics. This compound displays phase transition from para ferroelectric at about 260~K. Using multifrequency electron spin resonance in continuous wave and pulsed modes, we herein present the quantum dynamic of Mn$^{2+}$ ion probe DMAMgF. In paraelec...

Escherichia coli growing under anaerobic conditions produce H(2) and CO(2) by the enzymatic cleavage of formate that is produced from pyruvate at the end of glycolysis. Selenium is an integral part of formate dehydrogenase H (FDH H), which catalyses the first step in the formate hydrogen lyase (FHL) system. The genes of FHL system are transcribed only under anaerobic conditions, in the presence...

The hydrogenase and formate dehydrogenase levels in Syntrophobacter fumaroxidans and Methanospirillum hungatei were studied in syntrophic propionate-oxidizing cultures and compared to the levels in axenic cultures of both organisms. Cells grown syntrophically were separated from each other by Percoll gradient centrifugation. In S. fumaroxidans both formate dehydrogenase and hydrogenase levels w...

The demonstration by Lowy and Williams (2) that rabbit erythrocytes can incorporate C4-formate into the C-2 position of purines suggests by analogy with the well studied avian liver system (3) that Nro-formyltetrahydrofolate is the actual “lcarbon” donor. The synthesis of this compound is carried out by the formate-activating enzyme (also called tetrahydrofolate formylase (4, 5)) as shown in Eq...

Owing to the presence of crystallographic twofold rotation axes (site symmetry 2, Wyckoff letters e and f), the asymmetric unit of the title compound, [Mn(C(12)H(8)N(5))(CHO(2))](n), contains one-half of an Mn(II) cation, one-half of a bpt anion (Hbpt is 3,5-di-2-pyridyl-4H-1,2,4-triazole) and one-half of a formate anion. The bpt and formate ligands occupy the same C(2) symmetry, while the Mn(I...

In the title compound, C(22)H(28)F(2)NO(2) (+)·CHO(2) (-), there are three independent pyrrolidinium formate salt mol-ecules. In each cation, the central pyrrolidinium ring is not planar and the 2,5-disubstituted phenyl-ethyl groups are in equatorial positions. In the crystal, the ions are linked into a pair of chains parallel to the c axis by N-H⋯O hydrogen bonds between the NH group of the py...
