In a biochemistry course, the study of biomolecules focuses on four main classes: proteins, nucleic acids, carbohydrates, and lipids. Proteins are analyzed for their structure (primary to quaternary) and function, including enzyme activity and regulation. Nucleic acids, DNA and RNA, are explored in terms of their roles in genetic information storage, replication, transcription, and translation. Carbohydrates are examined as energy sources and structural components, while lipids are studied for their roles in energy storage, membrane structure, and signaling. Understanding these biomolecules is crucial for grasping their functions in biological systems and their impact on health and disease.
