Macromolecules and Their Functions

The video tutorial introduces macromolecules, the building blocks of life, found in all living organisms. It covers carbohydrates, lipids, and proteins, explaining their functions, types, and sources. Carbohydrates provide energy, with sugars burning fast and starches slowly. Lipids, or fats, store long-term energy and have roles in insulation and hormone regulation. Proteins are essential for muscle development and repair, made of amino acids, and found in various foods. The video concludes with a summary and credits.
