Biochemistry is the branch of science that explores the chemical processes within and related to living organisms. It is a multidisciplinary field that sits at the intersection of biology and chemistry, aiming to understand the molecular mechanisms that govern life. Biochemistry investigates how biomolecules such as proteins, carbohydrates, lipids, and nucleic acids interact, and how these interactions control biological processes from the cellular to the organismal level.Essentially, biochemistry provides the molecular foundation of life, explaining how cells function, how energy is produced and utilized, and how genetic information is stored, expressed, and transmitted. By studying the chemical processes in living systems, biochemists can understand diseases, develop drugs, improve agricultural productivity, and create new biotechnologies.Key areas in Biochemistry include:
