Carbohydrates And Lipids In Living Organisms

The video reviews organic molecules, focusing on carbohydrates and lipids. Carbohydrates, composed of monosaccharides, serve as a primary short-term energy source and provide structural components. Examples include starch and cellulose. Lipids, made of glycerol and fatty acids, store energy long-term, form waterproof coverings, and insulate animals. The video also discusses testing for these biomolecules in food.
