BME/CHE 250 Problem Set #7 Due: Thursday, November 18, 2010 (Unless you are presenting your project that week, then it is due the following week.) 1. Problem 6.2A new protein has been isolated by molecular biologists. Before they can measure its diffusion coefficient at 25oC, their instrument breaks and repairs will take six months? The researchers are in a panic because they need this information for a paper they are writing. The biologists do know that the molecule is spherical and has a radius of 12 nm. Before the instrument broke, they measured the diffusion coefficient of albumin (R = 3 nm and MW=68,000) as 6.8 x 10-7cm2s-1. Calculate the diffusion coefficient of the new protein.
