Question

Which of the following carbohydrates is the sweetest sugar?

• A. Glucose
• B. Fructose
• C. Cellulose
• D. Maltose

Hint:

Sweetness order among common sugars: \[ \text{Fructose}>\text{Sucrose}>\text{Glucose}>\text{Maltose} \] Fructose is commonly called fruit sugar.

Answer 1

The Correct Option is B

Concept: Carbohydrates are naturally occurring polyhydroxy aldehydes or ketones and their derivatives. Different carbohydrates possess different degrees of sweetness. The sweetness scale is usually compared relative to sucrose. Among the common monosaccharides, fructose is known to possess the highest sweetness.

Step 1: Examine glucose. Glucose is a monosaccharide and is sweet in taste. However, it is less sweet than fructose.

Step 2: Examine fructose. Fructose is a ketohexose commonly found in fruits and honey. It possesses the highest relative sweetness among naturally occurring sugars. \[ \boxed{\text{Fructose is the sweetest sugar}} \]

Step 3: Examine the remaining options. Cellulose is a structural polysaccharide and is not sweet. Maltose is less sweet than fructose. Therefore fructose remains the correct choice. Hence, \[ \boxed{\text{Correct Option }=(2)} \]
