What roles do polysaccharides play in living things?

Answers

Polysaccharides play crucial roles in living things due to their diverse functions and properties. As complex carbohydrates made up of multiple sugar units, they serve as important sources of energy and structural components in organisms.

1. **Energy Storage:** One primary role of polysaccharides is to store energy for short-term and long-term use. Plants store excess glucose in the form of starch, while animals store it as glycogen in the liver and muscles.

2. **Structural Support:** Polysaccharides provide structural support in cell walls of plants, algae, and some bacteria. For example, cellulose forms the rigid cell walls of plant cells, giving them shape and support.

3. **Protection and Lubrication:** Some polysaccharides, like chitin found in the exoskeletons of insects and crustaceans, provide protection and structural support. Hyaluronic acid, a polysaccharide in connective tissues, acts as a lubricant and shock absorber.

4. **Cell Recognition:** Polysaccharides are also involved in cell recognition and signaling processes. They form part of cell surface markers and play essential roles in immune responses and cell communication.

Overall, polysaccharides are essential biomolecules that fulfill diverse functions, contributing to the proper functioning and structure of living organisms.
