Course Introduction
Chemical Biology explores the interface between chemistry and biology, emphasizing how chemical techniques and principles are applied to understand and manipulate biological systems at the molecular level. This course covers topics such as the chemical structure and reactivity of biomolecules, enzyme mechanisms, small molecule probes, and the design of drugs and therapeutic agents. Students will learn how chemical tools are used to study cellular processes, map biological pathways, and develop innovative treatments for diseases, preparing them for advanced research in the rapidly developing field of chemical biology.
