Which of the following is an example of monosaccharides? A. Fructose B. Sucrose C. Starch D. Glucose
Both A and D
The correct answer is Both A and D — Fructose and Glucose.
Monosaccharides are the simplest carbohydrates that cannot be hydrolysed into smaller sugars. Common examples are glucose, fructose and galactose — all six-carbon (hexose) sugars.
Sucrose (table sugar) is a disaccharide made of one glucose and one fructose unit joined by a glycosidic bond, while starch is a polysaccharide composed of many glucose units in amylose and amylopectin chains. Hence, from the given list, only Fructose (A) and Glucose (D) qualify as monosaccharides.
