Step-by-step explanation:
Carbohydrates are defined as the compounds that consists of carbon, hydrogen and oxygen atom which are neutral in nature.
Carbohydrates are of three types. That is, monosaccharide, disaccharide, and polysaccharride.
Monosaccharide : Carbohydrates which contain only one or single monomer unit are known as monosaccharide. For example, glucose.
Disaccharide : Carbohydrates which contain two monosaccharide units or two monomer units are called disaccharides. For example, sucrose which is a sugar is a disaccharide.
Polysaccharide : Carbohydrates which contain more than two monomer units is known as a polysaccharide. For example, starch, glycogen etc are polysaccharides.
Thus, we distinguish the given groups as follows.
- Monosaccharide : single sugar molecule, glucose.
- Disaccharide : formed from two monosaccharide units, table sugar.
- Polysaccharide : three or more sugar molecules, starch.
