Question

Monosaccharides are classified into trioses and tetroses based on

• A. the number of carbon atoms
• B. the number of hydrogen atoms
• C. the number of sugar units
• D. the number of hydroxyl groups

Answer 1

The correct option is A the number of carbon atoms

Monosaccharides are the simple sugars that cannot be hydrolysed further to give simpler sugars. On the basis of number of carbon atoms, monosaccharides can be classified as triose (with 3 carbon atoms), tetrose (with 4 carbon atoms), pentose (with 5 carbon atoms), hexose (with 6 carbon atoms), septose (with 7 carbon atoms) and so on.
