- 1. Chemical biology is a multidisciplinary field that combines the principles of chemistry and biology to study biological systems at the molecular level. This field encompasses the design, synthesis, and application of small molecules, chemical probes, and drugs to investigate biological processes, pathways, and mechanisms. Chemical biologists use a variety of chemical tools and techniques to manipulate and study biological systems, such as enzymes, proteins, nucleic acids, and cell signaling pathways. By understanding the chemical interactions and dynamics within living organisms, chemical biology aims to uncover new insights into fundamental biological processes and develop innovative therapeutic strategies for treating diseases.
