A new nonlinear optical organic compound, namely, L-histidinium 2-nitrobenzoate (abbreviated as LH2NB (I); ([C(6)H(10)N(3)O(2)](+) [C(7)H(4)NO(4)](-))), was synthesized. The molecular structure of LH2NB (I) was elucidated using single crystal X-ray diffraction technique. The second harmonic generation (SHG) efficiency of this compound is about two times that of the standard potassium dihydrogen...

V. A. KNIVETT I954 3. [32P]Potassium dihydrogen phosphate was used to distinguish between ATP formed from ADP by the action of adenylate kinase (myokinase) and by synthesis involving inorganic phosphate. The appearance of 32P in ADP, and in both of the labile phosphates of ATP, but not in AMP, indicates the presence of adenylate kinase in extracts of Strep. faecali&. 4. The fission of citrullin...

Background: Erythromycin production often has concern with the consumption rate of amino nitrogen and phosphate, especially in the early fermentation phase. The dynamic regulation of nitrogen and phosphorus was put forward based on the comprehensive analysis of the contents of phosphorus and nitrogen in different nitrogen sources as well as the relations between nitrogen consumption and phospho...

A pyrrolylamidothiourea deprotonates in the presence of one equivalent of not only fluoride, but also acetate, benzoate or dihydrogen phosphate in DMSO solution with structural studies using synchrotron radiation confirming thiourea deprotonation in the solid state.

The preferential uptake of sulfate over the industrially important anions, chloride and nitrate and structurally similar dihydrogen phosphate has been achieved in aqueous media with a dicopper salicylaldoxime complex.

In the title salt, C(9)H(18)NO(2) (+)·H(2)PO(4) (-), the cyclo-hexane ring is puckered, the total puckering amplitude Q(T) being 0.555 (4) Å, and an intra-molecular N-H⋯O hydrogen bond generates an S(7) ring. In the crystal structure, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds lead to R(2) (2)(14), R(3) (3)(8) and R(4) (2)(8) rings, generating a two-dimensional layer.
