Reduced lateral mobility of a fluorescent lipid probe in cholesterol-depleted erythrocyte membrane
(Elsevier, 1980-03-27)
The effect of cholesterol depletion of the human erythrocyte membrane on the lateral diffusion rate of a fluorescent lipid probe is reported. At low temperatures (-5 to 5[deg]C), the diffusion of the probe is 50% slower ...
Vibrational analysis of peptides, polypeptides, and proteins. XXIV. Conformation of poly(Α-aminoisobutyric acid)
(Wiley Subscription Services, Inc., A Wiley Company, 1984-10)
Raman and polarized ir spectra have been obtained on built-up monomolecular films of poly(Α-aminoisobutyric acid), and analyzed in the context of normal mode calculations on 3 10 -, Α-, and Α′-helix conformations of this ...
Influence of counterions on the helical conformations of charged polypeptide chains
(Wiley Subscription Services, Inc., A Wiley Company, 1969-11)
No Abstract.
Vibrational analysis of peptides, polypeptides, and proteins. XXI. Β-Calcium-poly( L -glutamate)
(Wiley Subscription Services, Inc., A Wiley Company, 1984-08)
The observed Raman and ir spectra of Ca-poly( L -glutamate) in the Β conformation have been analyzed by means of a normal mode calculation. The force field for the main chain was transferred without refinement from Β-poly( ...
The magnetic susceptibility of spinach ferredoxin from 77-250[deg]K: A measurement of the antiferromagnetic coupling between the two iron atoms
(Elsevier, 1971-08-06)
The magnetic susceptibility of oxidized and reduced spinach ferredoxin has been measured over the temperature range 77-250[deg]K. Anomalous behavior is observed in both oxidation states and the data can be interpreted by ...
Infrared spectra of high polymers. V. Polyvinyl alcohol Presented in part at the Symposium on Molecular Structure and Spectroscopy, Columbus, Ohio, June 1956.
(Interscience Publishers, Inc.Wiley Periodiocals, Inc., 1956-11)
The infrared spectrum of polyvinyl alcohol has been investigated between 3600 and 70 cm. −1 . Polarization measurements on stretched specimens were made down to about 330 cm. −1 . The spectrum of a deuterated specimen ...
Surface enhanced raman spectroscopy of halide ions on colloidal silver: morphology and coverage dependence
(Elsevier, 1983-01-02)
Transmission electron microscopy shows that the colloidal silver used as a substrate for surface enhanced Raman spectroscopy consists of 75-135 A average diameter faceted crystals, which can be made to aggregate in clusters ...
Normal coordinate analyses of molecules with the amide group
(Elsevier, 1971-01)
Normal coordinate analyses have been performed on molecules with the amide group using force constants transferred from N-methylacetamides and polyamides. The molecules involved were hexamethylenedipropionamide, ...
Vibrational studies of the disulfide group in proteins : Part II. Ab initio force fields and normal mode frequencies of dimethyl, methylethyl, and diethyl disulfides
(Elsevier, 1990-07)
The geometric parameters and quadratic force constants of dimethyl disulfide, methylethyl disulfide, and diethyl disulfide in all their stable conformations and transition state conformations have been obtained from ab ...
Comprehensive force field for multiply-chlorinated hydrocarbons
(Elsevier, 1990)
A force field is presented that has been optimized for chlorinated hyrocarbons containing isolated, vicinal, and geminal secondary chlorines. For carbon--chlorine stretch modes, 74 frequencies in 10 molecules are reproduced ...
