Cross-peptide bond 13C---15N coupling constants by 13C and J cross-polarization 15N NMR
(Elsevier, 1979-07)
Comparative 13C---15N coupling constants are reported for the linear dipeptide tBoc--[U-13C]Ala-[15N]GlyOMe and the corresponding cyclic diketopiperazine, both in dimethylsulfoxide (DMSO) and, upon removal of the tBoc ...
Low-temperature phase transitions of Fe3O4 with innocuous dopants
(Elsevier, 1979-04)
Both Zn2+ and Cd2+ dopants on the A-sites in Fe3O4 lead to a loss in the furcation of the lambda anomaly at the Verwey transition but at markedly different dopant levels. Equilibrium adiabatic calorimetry from 5 to 350 K ...
Studies on hydroperoxide-dependent substrate hydroxylation by purified liver microsomal cytochrome P-450
(Elsevier, 1976-08)
Highly purified liver microsomal cytochrome P-450 catalyzes the hydroperoxide-dependent hydroxylation of a variety of substrates in the absence of NADPH, NADPH-cytochrome P-450 reductase, and molecular oxygen. The addition ...
Characterization of the [omega]-hydroxylase of Pseudomonas oleovorans as a nonheme iron protein
(Elsevier, 1977-10)
The [omega]-hydroxylase of Pseudomonas oleovorans, which catalyzes the hydroxylation of fatty acids and alkanes and the epoxidation of alkenes in the presence of a reduced pyridine nucleotide, a reductase, rubredoxin, and ...
Mitochondrial inner membrane in hypothyroidism
(Elsevier, 1976-02)
Inner membrane vesicles obtained from the liver mitochondria of hypothyroid and normal rats were compared. In the vesicles from hypothyroid rats the rate of ATP synthesis at 30 [deg]C is 35-50% less than the normal rate. ...
Low-temperature heat capacity of anisotropic crystals lamellar molybdenum disulfide
(Elsevier, 1976-01)
Heat capacities of natural molybdenite crystals were made to test the T2 limiting law for the heat capacity of a lamellar lattice near T --> 0. The findings are at variance with those of Smith et al. and accord with ...
Thermodynamics of the lanthanide halides II. Heat capacities and Schottky anomalies of SmCl3, EuCl3, and GdCl3 from 5 to 350 K
(Elsevier, 1977-01)
The heat capacities of SmCl3, EuCl3, and GdCl3 have been measured from 5 to 350 K by adiabatic calorimetry. For SmCl3 and EuCl3, the calculated Schottky heat capacities may be compared with the difference in heat capacity ...
Statistical survey of "saturation analysis" calibration curve data for prednisolone, prednisone and digoxin
(Elsevier, 1976-09)
An extensive survey of radioimmunoassay calibration data for prednisolone, prednisone and digoxin indicated that the common practice of preparing calibration curves with individual subject's pre-dose plasma or serum, and ...
