Exploring the Types of Carbohydrates

Carbohydrates are essential organic compounds made of carbon, hydrogen, and oxygen, primarily sourced from plants. They serve as energy sources and structural components. Carbohydrates are classified into three main types: monosaccharides, disaccharides, and polysaccharides. Monosaccharides are simple sugars like glucose, while disaccharides, such as sucrose and lactose, are complex sugars formed by condensation reactions. Polysaccharides, including starch and cellulose, are the most complex carbohydrates. Carbohydrates also play roles in forming other organic compounds and are involved in various biological functions.
