Protein---carbohydrate interaction. : Part XXII. A chemically-synthesized d-mannan and the interaction of some synthetic d-mannans with concanavalin A
(Elsevier, 1970-06)
1,6-Anhydro-[beta]--mannopyranose was polymerized in the presence of chloroacetic acid. A high-molecular-weight fraction insoluble in 80% ethanol was isolated and studied. Periodate-oxidation studies showed the polymer to ...
Heat capacities of bis-tetraethylammonium tetrachloronickelate and tetrachlorozincate I. Structural transitions and thermophysical results
(Elsevier, 1979-03)
The heat capacities of bis-tetraethylammonium tetrachloronickelate () and tetrachlorozincate () were measured over the temperature range 5 to 350 K by adiabatic calorimetry. Bifurcated anomalies were found for both compounds ...
Fractionation of the insoluble brain proteins with acrylamide electrophoresis
(Elsevier, 1970-03)
A method for fractionating the insoluble proteins of the brain with polyacrylamide electrophoresis is described. The procedure consists of dissolving the membrane proteins in a solution of urea, alkali, mercapto-ethanol, ...
Dynamic properties of fatty acid monomolecular films
(Elsevier, 1971-05)
Saturated fatty acids ranging from fifteen to twenty carbons in alkyl chain length were spread as insoluble monomolecular films and compressed continually at constant velocities. As these surface films assume close-packing ...
Biosynthesis of keratan sulfate: Purification and properties of a galactosyltransferase from bovine cornea
(Elsevier, 1979-02)
A soluble galactosyltransferase was purified 22,000-fold from bovine cornea. The enzyme catalyzes the transfer of galactose from UDP-galactose to N-acetyl--glucosamine, [alpha]- and [beta]-glucosaminides, bovine cornea and ...
Steady-state measurements of respiration rate with an oxygen electrode
(Elsevier, 1975-02)
An oxygen electrode was developed which measures steady-state respiration rates in a volume of 0.25 ml and at oxygen concentrations as low as 0.1 [mu]. The steady state was achieved by pumping air-equilibrated buffer into ...
The action of a binary nonionic detergent on a kidney membrane fraction
(Elsevier, 1976-08)
The disruption of a kidney cortex microsomal membrane preparation by a binary, nonionic detergent, was followed by using as markers, the changes in total protein content, and (Na+, K+)-ATPase in a supernatant fraction. ...
The oxidation of ethylene-1,2-d2 over a silver catalyst studied by microwave spectroscopy
(Elsevier, 1978-03-30)
Stereospecific ethylene-1,2-d2 was oxidized to ethylene oxide-1,2-d2 over Ag catalysts in a flow reactor at 180-280 [deg]C. The epoxide products did not completely randomize for any of the reaction conditions explored. ...
