Which of the following is an example of monosaccharides?

A. Fructose B. Sucrose C. Starch D. Glucose

The correct answer is Both A and D.

Key Points

• Hexoses, glucose, and fructose are the most common monosaccharides found in fruits and vegetables.
• Fructose is a monosaccharide, a form of sugar. Fructose, like other sugars, has four calories per gram.
• Fructose is often known as "fruit sugar" since it is found in many fruits naturally. Other plant foods that include it include honey, sugar beets, sugar cane, and vegetables.
• The main sugar in human blood is glucose. It is the human body's major source of energy and comes from the food you eat.
• Human blood transports glucose to all of the human body's cells for energy production. Diabetes is a condition in which blood sugar levels are abnormally high.​

Important Points

• Monosaccharides, often known as simple sugars, are the most basic sugar molecules (monomers) from which all carbohydrates are constructed.
• They are usually white, crystalline solids that are water-soluble. Only a few monosaccharides have a sweet flavour, despite their name (sugars).
• Disaccharides (such as sucrose and lactose) and polysaccharides are made up of monosaccharides (such as cellulose and starch).
• The common table sugar, sucrose, is a disaccharide that contains one molecule of each of the two monosaccharides D-glucose and D-fructose.
