Carbohydrates: Structure and Function

Dr. Trupti Ramteke introduces carbohydrates, their classification, and functions. Carbohydrates are essential energy sources, classified into monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Each type has unique characteristics and examples. The video also covers the functions of carbohydrates, including energy provision, storage, and structural roles.
