Carbohydrates Unpacked: Exploring Their Structure And Functions In Living Organisms

The video explains carbohydrates, a type of macromolecule composed of carbon, hydrogen, and oxygen in a 1:2:1 ratio. Carbohydrates serve as energy sources, storage, and structural components in organisms. The simplest carbohydrates are monosaccharides like glucose, fructose, and ribose. Disaccharides, such as sucrose and lactose, consist of two monosaccharides. Lactose intolerance occurs due to low lactase levels. Polysaccharides, including starch, glycogen, and cellulose, are formed from multiple monosaccharides. The video concludes with an invitation to explore more about macromolecules.
