Study Notes
Characteristics of Polysaccharides
- One characteristic of polysaccharides is that they are long-chain carbohydrates composed of many sugar molecules bonded together.
Functions of Polysaccharides
- The primary function of polysaccharides in living organisms is to provide energy and structural support.
Types of Polysaccharides
- Chitin is a type of polysaccharide commonly found in the exoskeletons of insects and crustaceans.
Chemical Composition of Polysaccharides
- Polysaccharides are composed of long chains of sugar molecules, specifically monosaccharides, bonded together through glycosidic bonds.
Polysaccharides in Animals
- Glycogen is a polysaccharide that serves as an energy storage molecule in animals.
Polysaccharides in Plants
- Cellulose is a polysaccharide that is a major component of the cell walls in plants.
