Biochemistry is the branch of science that explores the chemical processes and substances within living organisms. It delves into the structure, function, and interactions of biological molecules such as proteins, carbohydrates, lipids, and nucleic acids, as well as the metabolic pathways that govern their synthesis and breakdown.
By studying how molecules behave and interact in biological systems, biochemists seek to understand fundamental processes like metabolism, gene expression, and signal transduction, with applications ranging from medicine to agriculture and beyond.
