On the dehydration of trans-1,2-dihydrophthalic acid
(Elsevier, 1980)
The epimerization/dehydration of the title compound occurs by way of an enolization rather than a pair of concerted, suprafacial [1,5] hydrogen shifts.
Quasi-elastic light-scattering investigation of microemulsions
(Elsevier, 1980-09)
Quasi-elastic light scattering was used to investigate W/O microemulsions of heptane-AOT-(bis(2-ethylhexyl)sulfosuccinate sodium salt)-water and W/O and O/W microemulsions of hexadecane-SDBS (sodium dodecyl benzene ...
The kinetics of water exchange across the chloroplast membrane
(Elsevier, 1980-08-05)
The kinetics of water exchange across the membrane of class II chloroplasts has been studied by two NMR methods. Both methods utilize Dy(en)3+ (en = ethylenediamine) to induce a transmembranal chemical shift the order of ...
Induction of tyrosine aminotransferase and amino acid transport in rat hepatoma cells by insulin and the insulin-like growth factor, multiplication-stimulating activity : Mediation by insulin and multiplication-stimulating activity receptors
(Elsevier, 1980-10-01)
Insulin stimulates a 2-fold increase in the amount of tyrosine aminotransferase and a 5-10-fold increase in the rate of amino acid transport in dexamethasone-treated rat hepatoma cells. In order to determine whether these ...
The stereochemistry of ethylene-1,2-d2 epoxidation over silver catalysts
(Elsevier, 1980-10)
The stereochemistry of the catalytic epoxidation of cis-ethylene-1,2-d2 to ethylene oxide over four unsupported and two supported silver catalysts as well as over Ag2O and AgO was studied. Variations of the stereochemistry ...
Structure of the dextran of Leuconostoc mesenteroides B-1355
(Elsevier, 1980-09-15)
The structure of dextran B-1355-S (soluble fraction) has been investigated. Acid hydrolysis of the methylated dextran yielded 2,3,4,6-tetra-, 2,3,4-tri-, 2,4,6-tri-, and 2,4-di-O-methyl--glucose, in the molar ratios of ...
The soluble components of chromaffin granules a carbon-13 NMR survey
(Elsevier, 1980-07-03)
Carbon-13 NMR spectra of the reconcentrated chromaffin granule lysate have been obtained at 50 MHz and 62.9 MHz. The spectrum contains a number of assignable resonances in addition to those of the main soluble components ...
