Biochemistry is a branch of science that explores the chemical processes and substances that occur within living organisms. As a course, it serves as a bridge between biology and chemistry, focusing on understanding the molecular mechanisms behind various biological functions. Students study the structure and function of biomolecules such as proteins, lipids, carbohydrates, and nucleic acids, along with the metabolic pathways they participate in. The course also delves into enzyme activity, gene expression, and regulation, as well as cell signaling and molecular genetics. Through lectures, laboratory experiments, and problem-solving sessions, students gain insight into how life is sustained at the molecular level, which is essential for fields such as medicine, pharmacology, and biotechnology.
