Definition - What does Polysaccharides mean?

A polysaccharide is a molecule that is built by a collection of monosaccharides, which can range from ten to thousands.

There are three types of polysaccharides: cellulose, hemicellulose and pectin.

Present in both humans and plants, this molecule is used in many ways, including for storing energy, providing support to cells and sending cellular messages. These molecules are integral for humans as well as the environment.

MaximumYield explains Polysaccharides

Polysaccharides are present in the cell walls of plants and are vital to optimal plant development. During photosynthesis, the plant absorbs carbon dioxide. This helps with the biosynthesis of cell walls.

Polysaccharides enable this by being present in the cell walls. This process allows plants to reduce carbon emissions and improve air quality. However, the complexity of polysaccharides in biosynthesis is still in need of further research.

Polysaccharides contribute to both nutritional and sensorial properties in plants. These complex long-chain molecules are a combination of glycosidic linkages and simple sugar molecules. As a result, it is responsible for the physiological aspects of plants. This molecule is broadly used due to its thickening, stabilizing and gelling properties.

Once in the storage stage, there are two types of polysaccharides: starch and fiber. Both of these are vital for humans. Starch is found in cereals grains and breaks down to glucose in the human body, while fiber is found in whole grains and helps with food passage in the gut.
