Question

Which one is the sweetest sugar?
a. Glucose
b. Fructose
c. Sucrose
d. Maltose

Answer 1

Hint: The sugar which is found in the fruits is the sweetest sugar. It is also known as fruit sugar or levulose.

Complete answer:
To solve the question we must know about the various sugars.
Glucose is a monosaccharide. It consists of 6 carbon atoms in its structure. It is the most abundant sugar present in nature. It is the end product of photosynthesis.
Fructose is also a monosaccharide sugar. It also consists of 6 carbon atoms in its structure. It is the sugar which gets directly absorbed into the bloodstream. Fructose is most readily soluble in water amongst all the sugars.
Sucrose is a disaccharide which is formed from one α-D glucose and one β-D fructose.
Maltose is also a disaccharide sugar which is formed from two molecules of D-Glucose. It reduces sugar.

The sweetness of these sugars depends on the sweetness perception rating of these sugars. This rating comes out to be 1 for sucrose, 1.7 for fructose, 0.74-0.80 for glucose and 0.33-0.45 for maltose.
So from the above data it is very clear that the sweetness perception rating of fructose is the highest and so fructose is the sweetest sugar.

Hence, the correct answer to this question is fructose.

Note:
Fructose or fruit sugar is found in honey, berries, and flowers. Watermelon, asparagus, peas, grapes and zucchini are some of the fruits and vegetables which have high fructose content.
