What is the difference between monosaccharides and polysaccharides?

Monosaccharides:

1. Monosaccharides are small carbohydrate compounds consisting of simple units of carbon, hydrogen, and oxygen;
2. The monosaccharide molecular formula is (CH2O) n, where n is a small number that varies from 2-10
3. Monosaccharides cannot be further hydrolyzed because they are presented in the simplest form,
4. Monosaccharides are colorless, sweet taste, crystalline appearance, sweet taste is completely absent in polysaccharides, although they are made from various monosaccharide units, they can be homopolysaccharides or heteropolysaccharides.
5. Monosaccharides are water soluble, but not soluble in nonpolar solvents;
6. Consists of the simplest carbohydrate units, namely carbon, hydrogen, and oxygen;

Polysaccharides:

1. Polysaccharides are large carbohydrate compounds consisting of many monosaccharide units connected by glycosidic bonds.
2. Polysaccharides have Cx (H2O) y, where x is usually a large number between 200-2500
3. Polysaccharides cannot be further hydrolyzed because they contain 2 or more monosaccharide units, which can then be hydrolyzed into oligosaccharides, or monosaccharides.
4. polysaccharides are not soluble in water
5. Polysaccharides consist of many (several thousand) monosaccharide units.
6. Monosaccharides are the main energy source of energy, which provides about 4 calories (kilocalories) per gram;
7. Polysaccharides are structural components of cell walls and act as energy reserves.
