No, glucose is not a polysaccharide. It is a simple sugar, also known as a monosaccharide.
Polysaccharides are long chains of monosaccharide units bonded together. They can comprise hundreds or thousands of glucose units and are typically used by organisms as a form of energy storage or structural support. Examples of polysaccharides include starch, glycogen, and cellulose.
Glucose, on the other hand, is a single sugar molecule that serves as a primary energy source for most living organisms. It can be linked together with other glucose molecules to form polysaccharides, but by itself, it remains a monosaccharide.
