Which type of saccharide is glucose classified as?

Glucose is classified as a monosaccharide because it is the simplest form of carbohydrate. Monosaccharides consist of single sugar units and cannot be hydrolyzed into simpler sugars. Glucose, specifically, has a molecular formula of C6H12O6 and plays a fundamental role in metabolism as a primary energy source for cells. It is a building block for more complex carbohydrates but does not combine with other sugars to form disaccharides or polysaccharides in its pure form. For instance, when two monosaccharides like glucose and fructose combine, they form sucrose, which is a disaccharide. Therefore, identifying glucose as a monosaccharide highlights its basic structure and role in nutrition.
