Question

# Select the correct option:How many carbon atoms are generally used in composition of monosaccharides?

A
3 to 7
B
1 to 5
C
5 to 10
D
5 to 15

Solution

## The correct option is A 3 to 7Carbohydrates are also called saccharides because their basic components are sugars. Monosaccharides are those sugars or simple carbohydrate monomers which cannot be hydrolysed further into smaller components. They have a general formula of $$C_nH_{2n}O_n$$. Depending upon the number of carbon atoms, monosaccharides are of five types : trioses (having 3 carbon atoms, glyceraldehyde), tetroses (having four carbon atoms, e.g., erythrose), pentoses (having five carbon atoms, e.g, ribose), hexoses (having six carbon atoms, e.g.; glucose), heptoses (having seven carbon atoms, e.g., sedoheptulose).So, the correct answer is '3 to 7'.Biology
