Which field of chemistry involves the study of chemical reactions involved in biological processes?

The field of chemistry that focuses specifically on the chemical reactions and processes that occur within living organisms is biochemistry. Biochemistry examines the molecular mechanisms that underpin biological functions, such as the structure and function of proteins, nucleic acids, carbohydrates, and lipids. It combines principles from both biology and chemistry to understand how these biological molecules interact and cooperate in processes like metabolism, cell signaling, and genetic information transfer.

By contrast, organic chemistry primarily deals with the study of carbon-containing compounds and their reactions, while inorganic chemistry focuses on inorganic compounds, which generally do not contain carbon-hydrogen bonds. Analytical chemistry is dedicated to the techniques and methods used to determine the composition of substances but does not specifically center on biological processes. Thus, biochemistry is the most relevant and accurate choice for understanding the chemical reactions that take place in biological systems.
