Chemical biology refers to the study of the chemical processes that occur within living organisms. The field of chemical biology is wide-ranging, and includes a number of different research areas such as biochemistry, molecular biology, and biophysics. There are several synonyms that are used to describe the field of chemical biology, including biochemical sciences, molecular science, and chemical genetics. Each of these terms highlights a different aspect of the field, with biochemical sciences emphasizing the chemical nature of biological processes, molecular science highlighting the importance of molecular interactions, and chemical genetics emphasizing the role of chemistry in the study of genetics and gene expression. Regardless of the terminology used, chemical biology remains a critical area of research for understanding the fundamental processes of life.
