The Hemoglobin Of Tubifex Tubifex, Lalitchandra Vrajlal Vora
The Hemoglobin Of Tubifex Tubifex, Lalitchandra Vrajlal Vora
Masters Theses
The hemoglobin of Tubifex tubifex is found in solution in the blood of the worm in cells as in vertebrates. The binding of oxygen to the hemoglobin can be followed spectrophotometrically. A peak of absorbtion at 540 nm is fairly constant under different condition, while a peak at 575 nm disappears from the spectrum when oxygen is removed. The hemoglobin contains heme, non-heme iron and protein.
Binding of oxygen to the hemoglobin was found to be dependent on the concentration of the hemoglobin, at low concentrations (4.16 x 10-6 M), oxygen could not be removed from the hemoglobin. Only …
The Conductance Of Some Non-Rigid Bolaform Electrolytes, William Terry Schmidt
The Conductance Of Some Non-Rigid Bolaform Electrolytes, William Terry Schmidt
Masters Theses
Bolaform electrolytes are those which contain two or more charges separated by an inert framework. These are intermediate in structure between simple electrolytes and polyelectrolytes. Since these are similar to both synthetic and biological electrolytes, this investigation has been undertaken to determine some of their properties in solution.
The sodium and magnesium salts of ethane, propane, butane, pentane, hexane and decane α,ω-disulfonates were prepared. Each acid was prepared by refluxing the α,ω-dibromide of the desired salt with sodium sulfite. The sodium and magnesium salts were prepared by ion-exchange techniques.
The conductance of each salt was determined in methanol utilizing the …
Equilibrium And Kinetic Study Of The Substitution Reactions Of Pentacarbonylaminetungsten (O) With Triphenylphosphine, William O. Bailey
Equilibrium And Kinetic Study Of The Substitution Reactions Of Pentacarbonylaminetungsten (O) With Triphenylphosphine, William O. Bailey
Masters Theses
A kinetic and equilibrium study of the reaction of triphenylphosphine (PPh3) with pentacarbonylaminetungsten (O) [(CO)5WNH2C6H5] has been reported previously. Equilibrium constants for the reaction (CO)5WNH2C6H5 + PPh3 = (CO)5W[P(C6H5)3] + C6H5NH2 in toluene were reported to be 17.1, 49.2 and 65.7 respectively. In addition, the entropy change (ΔS) for the reaction was found to be 86±5 cal mol-1 deg-1.
In this study the above reaction was …
