Proteins are organic compounds that are vital to living cells, serving important functions like catalyzing reactions and providing structure. Lipids include fats, waxes, and other molecules that store energy, form cell membranes, and act as signaling molecules. The document discusses the major macronutrients - proteins, carbohydrates, lipids, vitamins, and minerals - that make up a balanced diet and provide nutrients to the human body.

9. Lipids Lipids are a broad group of naturally-occurring molecules which includes fats , waxes , sterols , fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides , diglycerides , phospholipids , and others. The main biological functions of lipids include energy storage, as structural components of cell membranes , and as important signaling molecules .

10. Vitamins A vitamin is an organic compound required as a nutrient in tiny amounts by an organism . A compound is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from the diet.
