Carbohydrate Classification and Properties

The video tutorial covers the classification of carbohydrates into three main groups: monosaccharides, oligosaccharides, and polysaccharides. Monosaccharides are the simplest form, further divided into aldoses and ketoses. Oligosaccharides consist of 2-10 monosaccharide units, with examples like sucrose and lactose. Polysaccharides are long chains of monosaccharides, classified into homopolysaccharides and heteropolysaccharides, with examples such as starch and cellulose.
