Comments "A second consequence of the close packed interior of proteins is that all proteins have approximately the same density, about 1.37 g/cm^3. For most of the following, [researchers] will use the partial specific volume, v2, which is the reciprocal of the density. v2 varies from 0.70 to 0.76 for different proteins, and there is a literature on calculating or determining the value experimentally. For the present discussion, [researchers] will ignore these variations and assume the average v2= 0.73 cm^3/g."
