Exploring the Structure of Carbohydrates

The video tutorial explains the structure of carbohydrates, which include carbon, hydrogen, and oxygen in a 1:2:1 ratio. It covers three types of carbohydrates: monosaccharides, disaccharides, and polysaccharides. Monosaccharides like glucose, fructose, and galactose are simple sugars, while disaccharides such as sucrose, maltose, and lactose are formed by bonding two monosaccharides. Polysaccharides, including starch, glycogen, and cellulose, are complex carbohydrates formed by bonding many monosaccharides. The video also highlights the role of carbohydrates in the body and their dietary sources.
