The diffusion coefficient, D, of a rigid spherical molecule is given by the equation KT Dua 6 where n is the viscosity of the solvent, r is the radius of the sphere, k is the Boltzman constant 1.38 x 10-6 erg.K-, and T is the absolute temperature in kelvins. Assume that this protein is an unhydrated, rigid sphere with a density, p, of 1.35g.cm . Calculate the diffusion coefficient of a 100 kDa protein in a membrane that has an...

The diffusion coefficient for horse hemoglobin in water is 1.26 × 10–10 m2 s–1 at 40 °C. The viscosity of water at 40 °C is 0.653 × 10–3 kg m–1 s–1. Estimate the radius of hemoglobin assuming the molecule to be spherical and obey Stokes’s law. Comment on the size of Hemoglobin to a corona virus unit which has a diameter of 120 nm.
