What is the diffusion coefficient of sucrose?
What is the diffusion coefficient of sucrose?
The sharp decrease at 70–75% RH, where the diffusion coefficient of water is ∼10–11 m2 s–1, the diffusion coefficient of sucrose is ∼10–13 m2 s–1 and the viscosity is ∼5 Pa s, occurs where the solution is highly fluid.
How is hydrodynamic radius measured?
A value of the hydrodynamic radius can be calculated from measurements of the diffusion coefficient by means of the Stokes−Einstein equation. However, here we have used a different approach and have included a reference molecule in the protein solution ( 27).
What is meant by hydrodynamic radius?
The effective radius of an ion in a solution measured by assuming that it is a body moving through the solution and resisted by the solution’s viscosity. If the solvent is water, the hydrodynamic radius includes all the water molecules attracted to the ion.
Is sucrose aqueous?
Sucrose or table sugar (C12H22O11) is a good example of a polar compound that readily dissolves in water, forming an aqueous solution.
What is the molar mass of sucrose?
342.3 g/molTable sugar / Molar mass
C12H22O11 has a molecular weight of 342.299 amu. A mole of C12H22O11 would have a mass of 342.299 grams. This quantity is known as the molar mass, a term that is often used in place of the terms atomic weight or molecular weight.
What is hydrodynamic volume?
Hydrodynamic volume – the volume of a polymer coil when it is in solution. This can vary for a polymer depending on how well it interacts with the solvent, and the polymer’s molecular weight.
What is hydrodynamic radius of polymer?
Note that in biophysics, hydrodynamic radius refers to the Stokes radius, or commonly to the apparent Stokes radius obtained from size exclusion chromatography. The theoretical hydrodynamic radius. arises in the study of the dynamic properties of polymers moving in a solvent.
What is the difference between hydrodynamic radius and radius of gyration?
The radius of gyration is typically calculated from static scattering measurements, while the hydro- dynamic radius (or equivalent sphere radius) is deter- mined by dynamic light scattering or other diffusion measurements.
What is the chemical formula of sucrose?
C12H22O11Table sugar / Formula
Why is the formula for sucrose C12H22O11?
Sucrose is a molecule composed of two monosaccharides, namely glucose and fructose. This non-reducing disaccharide has a chemical formula of C12H22O11. Sucrose is commonly referred to as table sugar or cane sugar. In a C12H22O11 molecule, the fructose and glucose molecules are connected via a glycosidic bond.
What is the formula of sucrose?
C12H22O11Table sugar / Formula
C12H22O11 is the chemical or molecular formula for sucrose, meaning each sugar molecule contains 12 atoms of carbon, 22 atoms of hydrogen and 11 atoms of oxygen.
