What do we know about the basis of biomolecular activity  

Most biological effects are reversible in the short term. The majority of effects of chemicals on biological systems are to some extent reversible in short-term experiments. For 

These factors are each providing clues about the way in which small molecules (roughly speaking chemicals with a molecular weight of less than rooo) cause their biological effects if indeed they show any effect. One well-established chemical law. The Law of Mass Action, underlies these findings and, as we shall see a little later, this law guides us to the new model of NP diversity.
