Is fructose a monosaccharide, disaccharide, or a polysaccharide

Fructose is a monosaccharide.

Explanation:

The carbohydrates are classified as simple carbohydrate and complex carbohydrate. The simple carbohydrate is in turn classified as monsaccharide and disaccharide.

The monosaccharide are types of carbohydrates that cannot be hydrolyzed. Sugars such as glucose, fructose and galactose are well-known examples of monosaccharide as they cannot be hydrolyzed into simple products.

When fructose is combined with glucose it leads to the formation of disaccharide called sucrose.
