Lipids are a diverse group of biomolecules critical for cell structure, signaling, and metabolic regulation, with phospholipids, steroids, and prostaglandins playing distinct roles in the body. This image provides a detailed visual representation of these lipids, showcasing the structure of phosphatidylcholine (a phospholipid), cholesterol (a steroid), and prostaglandins like PGF2α and PGE2. Exploring these structures offers a deeper understanding of their functions in physiological processes and health.
