^Stuart L. Schreiber, K.C. Nicolaou. What's in a name?. Chemistry & Biology. 1997, 4 (1): 1–2. "Chemical biology powerfully complements molecular biology; while molecular biology allows the function of biological molecules such as proteins and nucleic acids to be altered by mutation, chemical biology directly alters the function of biological molecules by chemical means, for example by using small molecules or designed molecules as ligands. To us. this is the core of the field of chemical biology."
