This very useful equation shows that plotting the left-hand side against cmm should yield a straight line whose intercept is 1/Mmm and whose slope is the quantity in parentheses, which is called the osmotic second virial coefficient. The slope can be either positive or negative. The former indicates repulsion of two macromolecules and the latter is characteristic of attractive forces between them. As can be seen in Fig. 11.18, common proteins obey Eq (11.41) very closely. The corresponding values of Mmm and bmm are shown in the table below the graph. The osmotic second virial coefficient (more precisely, the nonideality coefficient bmm) is very useful in analyzing the separation and purification of proteins (Sect, il.8)"

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
