Biochemistry is a scientific discipline that explores the chemical processes and substances that occur within living organisms. As a course, it bridges the fields of biology and chemistry, providing a molecular-level understanding of how biological systems function. Students learn about the structure and function of biomolecules such as proteins, nucleic acids, carbohydrates, and lipids, as well as the metabolic pathways that sustain life. The course typically covers enzyme activity, genetic information flow, cellular respiration, and biochemical signaling. It also emphasizes laboratory techniques used in modern biochemical research. Biochemistry is essential for fields such as medicine, pharmacology, and biotechnology, making it a foundational subject for students pursuing careers in health and life sciences.
