जब किसी विलयन में महाआण्विक संकुलन (macromolecular crowding) बढ़ता है, तो प्रोटीन का रासायनिक विभव (chemical potential) ________ है।

A protein has a sedimentation coefficient value of 3.12 × 10-13 sec in water and a diffusion coefficient of 8.2 × 10-7 cm2/sec. Both values are determined at 20°C in water. If the partial specific volume of the protein is 0.735 cm3/g and the density of water at 20°C is 0.998 g/cm3, the molecular weight of the protein (using R = 8.314 × 107 erg/mol·K) is approximately:
