Hemoglobin has a MW of 64,460. Estimate its molecular radius in nm, and estimate the diffusivity in water at 37 C from both (A) the Renkin and Curry empirical equation (shown in class) and (B) the Stokes-Einstein equation. Assume =1 g/cm³ and =0.76 cP. (Hint: for one answer you will need to find the diffusion coefficient first then the molecular radius; for the other answer you will find the molecular radius first, then the diffusion coefficient). Compare the radii values you calculated to values reported by online literature sources. (Ans: a = 2.94 nm -> D = 10.16 x 10^-7 cm²/s)
