Lipids play crucial roles in biological systems, with four main types: fats, phospholipids, waxes, and steroids. Fats, composed of triglycerides, serve primarily as a long-term energy store and insulate the body while providing cushioning for organs. Phospholipids form the fundamental structure of cell membranes, creating a barrier that regulates the flow of substances in and out of cells. Waxes, known for their hydrophobic properties, provide protective coatings on plant leaves and animal fur, helping to reduce water loss and protect against environmental hazards. Steroids, characterized by their four-ring structure, function as hormones and signaling molecules, playing essential roles in regulating metabolism, immune responses, and reproductive processes. Together, these diverse lipid types contribute to the overall functionality and integrity of living organisms.
