Summary

The generally successful model of liquid water, with its range of hydrogen bond strengths from weak to strong, fails to account for much of biochemistry. In particular it cannot supply the compensating decrease in free energy required to balance decreases in entropy in well-explored processes such as protein folding in solution. A simplified model in which there are just two strengths of hydrogen bonds seems to account as well for the broad bands of the vibrational spectrum of water, and at the same time has an inbuilt reservoir of free energy which can be harnessed to balance the decrease in entropy and increase of complexity of so many biochemical processes.
