Exercise 2: Phosphatidylcholine is a lipid that can be found in

Exercise 2: Phosphatidylcholine is a lipid that can be found in egg yolk. When phosphatidylcholine is mixed with water it will form micelles - spherical "particles". Molecular mass (Mm) for the particles is 97000g/mole Density (p) for the particles is 1.018g/cm3 The temperature is 25C a) What is the radius for the particles? Assume that the particles are not hydrated. The viscosity of water () at the given temperature is 0,9mPas (milliPascal second) Boltzmann constant: 1,381023J/K (Pa=kg/ms2 and J=kgm2/s2 ) b) Calculate the diffusion coefficient (D) for the particles in water Under similar conditions, the diffusion coefficient has been determined experimentally to be 6.547107cm2/s. c) Explain the reason for the difference between the calculated and experimental values. d) Calculate f0f
