Lipids and carbohydrates are two of the four primary macromolecules essential for life. Lipids include fats, oils, waxes, and steroids, and are primarily used for energy storage, membrane structure, and signaling. Carbohydrates, which include sugars and starches, serve as a primary energy source and play roles in structural components and cell recognition. Both macromolecules are vital for cellular function and overall metabolism.
