Detailed explanation-1: -A monosaccharide features a skeleton of carbon atoms and the minimum number of carbon atoms is three.

Detailed explanation-2: -Monosaccharides with three carbon atoms are called trioses and these are the smallest monosaccharides, such as dihydroxyacetone and d-and l-glyceraldehyde.

Detailed explanation-3: -Six-carbon monosaccharides are prevalent but monosaccharides can have from three to seven carbons in their structures (three carbons, triose; four carbons, tetrose; five carbons, pentose, six carbons, hexose; and seven carbons, heptose). The hexoses are common and important.

Detailed explanation-4: -All the monosaccharides have the formula as (CH2O) n. Here, the two hydrogen atoms and one oxygen atom associate itself to the central carbon molecule.

Detailed explanation-5: -Monosaccharides are made up of single unit composed of 3 to 7 carbon atoms, e.g., glyceraldehyde, erythrose, ribose, glucose, fructose, sedoheptulose.
