A2.1.1 Introduction to Carbohydrates and Lipids 🍞🧈 (Demo)

Carbohydrates and lipids are essential organic molecules that play key roles in living organisms. Carbohydrates provide a quick and accessible source of energy and can also serve structural functions, such as forming cell walls in plants. They range from simple sugars like glucose to complex polysaccharides like starch and cellulose. Lipids, which include fats and oils, are used mainly for long-term energy storage, insulation, and cell membrane structure. Together, these molecules supply energy, support growth, and help maintain vital biological functions.
