Structural correlations of the lanthanide halides and related compounds. Derivatives of the anti-nickel-arsenide structure
(Elsevier, 1976-07)
An examination of structural data for lanthanide halides and related compounds has shown that a substantial number of different structure types are conveniently described as layered structures derived from anti-NiAs by ...
Variant properties of bovine liver 2-keto-4-hydroxyglutarate aldolase; its [beta]-decarboxylase activity, lack of substrate stereospecificity, and structural requirements for binding substrate analogs
(Elsevier, 1971-10-20)
1. 1. 2-Keto-4-hydroxyglutarate aldolase (2-oxo-4-hydroxyglutarate glyoxylatelyase; reaction: 2-oxo-4-hydroxyglutarate [left harpoon over right] pyruvate + glyoxylate) catalyzes the cleavage and the formation of both optical ...
Phosphatidate phosphatase : Activity and properties in fetal and adult rat lung
(Elsevier, 1978-09-28)
The purpose of this work is to compare the properties of phosphatidate phosphatase (-[alpha]-phosphatidate phosphohydrolase, EC 3.1.3.4) in fetal and adult rat lung and to establish the developmental profile of activity ...
Solution behavior, circular dichroism and 220 MHz PMR studies of the bovine myelin basic protein
(Elsevier, 1975-09-09)
Bovine myelin basic protein has been investigated with regard to its solution behavior, circular dichroism and 220 MHz PMR spectral properties.At pH 4.8 [gamma]/2 = 0.1 acetate buffer, light scattering yielded a Mr of 17 ...
Iron-ATP, a by-product of acid extraction of whole blood or red blood cells
(Elsevier, 1973-09-14)
Trichloroacetic acid extracts of red cell often produce an iron-ATP complex after ion exchange chromatography of the extract amounting to about 1/3 of the total ATP. In the present work the presence of 14-50% of iron-ATP ...
Molecular structure of F2POPF2: an electron diffraction study
(Elsevier, 1975-09)
The most important geometric parameters and associated uncertainties (2[sigma]) determined for F2POPF2 are the distances (rg) P-O = 1.631 +/- 0.010 A, P-F = 1.568 +/- 0.004 A, and angles POP = 135.2 +/- 1.8[deg], OPF = ...
Isoenzymes of carbonic anhydrase I from primate red blood cells
(Elsevier, 1971-04-27)
The electrophoretic patterns of the multiple forms of carbonic anhydrase I were examined from the red cells of two species of macaque monkeys and orangutan. In the rhesus macaque, Macaca mulatta, it was possible to generate ...
Thermophysical measurements on transition-metal tungstates I. Heat capacity of zinc tungstate from 5 to 550 K
(Elsevier, 1975-10)
Redetermination of the heat capacity of ZnWO4 after chemical removal of the ZnO phase from a previous sample has provided better values for chemical thermodynamic properties. At 298.15 K Cp, So, and -{Go(T) - Ho(0)}/T are ...
Thermodynamics of polynuclear aromatic molecules I. Heat capacities and enthalpies of fusion of pyrene, fluoranthene, and triphenylene
(Elsevier, 1971-01)
The heat capacities of three crystalline condensed-ring aromatic substances were studied from 5 to 350 K by adiabatic cryogenic calorimetry and into the liquid phase with the intermediate-range adiabatic calorimeter. The ...
