Disaccharides vs. Polysaccharides
Main DifferenceThe main difference between Disaccharides, and Polysaccharides is that the Disaccharides are made up of two monomers, and Polysaccharides are made up of an enormous number of monomers.
Difference Between Disaccharides and Polysaccharides
Disaccharides vs. Polysaccharides
Disaccharides are usually soluble in water, while polysaccharides are generally insoluble in water.
Disaccharides vs. Polysaccharides
Disaccharides also sweet in taste; on the other hand, polysaccharides are not sweet.
Disaccharides vs. Polysaccharides
Disaccharides are act as reducing sugars; on the contrary, polysaccharides ae always acts as non-reducing sugars.
Disaccharides vs. Polysaccharides
Disaccharides are usually consisting of two monomers; on the flip side, polysaccharides contain a large number of monomers.
Disaccharides vs. Polysaccharides
Disaccharides contain linear, branched or unbranched, and simple chemical structure, while polysaccharides contain the chemical structure as branched or complex structures.
Disaccharides vs. Polysaccharides
Two ring structures are present in disaccharides; on the other hand, several ring structures are present in polysaccharides.
Disaccharides vs. Polysaccharides
The general formula of disaccharides is (CH2O) n, where n could be from 2 to 10, while the general formula for polysaccharides is (CH2O) y, where n could be more than between 200-2500.
Disaccharides vs. Polysaccharides
Disaccharides are used by plants to carrying molecules like fructose, lactose, and glucose between cells of plants; on the contrary, polysaccharides act as an energy reservoir and refer as the structural constituent in cell walls of plants.
Disaccharides vs. Polysaccharides
The molecular weight of disaccharides as compare to monosaccharides is comparatively larger; on the other hand, polysaccharides contain comparatively larger molecular weight as compare to all other molecules.
Disaccharides vs. Polysaccharides
Foods use an example in disaccharides are table sugar or are found in beetroot; conversely, some examples of food in polysaccharides are oats, buckwheat, brown rice, etc.

Disaccharides vs. Polysaccharides
Disaccharides are considered as molecules of sugar made up of monosaccharides, and polysaccharides are considered as carbohydrate molecules composed of several molecules of monosaccharides linked with glycosidic bonds. Most of the disaccharides are usually soluble in water, whereas polysaccharides are generally insoluble in water. Disaccharides also sweet in taste; on the contrary, polysaccharides are not sweet.

What are Disaccharides?
Disaccharides are referred to as sugar molecules that are made up of two monosaccharides. Hence, every molecule of disaccharide formed of two chemical rings. The bond or link present among two monosaccharides is known as a glycosidic bond.
Disaccharides are also known as simple sugars. All disaccharides are dissolved in water and colorless or dull when soluble in water. Some of the disaccharides could sweet in taste, but some not act as sweet.
Significance of disaccharides Is that they are used by plants to transport molecules like fructose, lactose, and glucose between cells of plants. Various examples are sucrose, lactose, and maltose. Food uses an example in disaccharides are table sugar, found in beetroot, or add in food for sweetness.
Types
- Reducing Sugars: Could perform as a reducing agent
- Non-Reducing Sugars: Cannot perform as a reducing agent
What are Polysaccharides?
A polysaccharide is considered a carbohydrate that is composed of several monosaccharides through glycosidic bonds. They are an extensive series of monosaccharide molecules. Hence, all the polysaccharides are formed of several chemical rings.
The composition of polysaccharides happens by polymerization condensation because a molecule of water is produced by every glycosidic bond. Many polysaccharides are usually insoluble in water and do not contain a sweet taste. Because of the complex structure of polysaccharides, they all act as non-reducing agents.
Polysaccharides contain the chemical structure as branched or complex structures. Some of the polysaccharides’ examples are starch and cellulose.
Classification
- Homo-Polysaccharides: Composed of only one type of monosaccharides
- Hetero-Polysaccharides: Composed of two or more types of monosaccharides
ConclusionAbove discussion concludes that the disaccharide, and polysaccharides are major constituents in nature where disaccharides are made up of monomers, whereas polysaccharides made up of a large number of monomers.
