Biochemistry is a branch of science that explores the chemical processes and substances that occur within living organisms. It delves into the structure, function, and interactions of biological macromolecules, such as proteins, nucleic acids, carbohydrates, and lipids, which are crucial for life. This article provides an introduction to biochemistry, focusing on the cell and its biochemical organization, the transport process across cell membranes, and the significance of energy-rich compounds like ATP and cyclic AMP.
