Explanation:
Detailed explanation-1: -A monosaccharide features a skeleton of carbon atoms and the minimum number of carbon atoms is three.
Detailed explanation-2: -Step 3: Formula of three carbon monosaccharides Thus, the formula for trioses is (CH2O)3, i.e., C3H6O3. Glyceraldehyde or dihydroxyacetone has the formula C3H6O3. These two three-carbon monosaccharides are trioses; glyceraldehyde is an aldotriose, and dihydroxyacetone is a ketotriose.
Detailed explanation-3: -Monosaccharides are made up of single unit composed of 3 to 7 carbon atoms, e.g., glyceraldehyde, erythrose, ribose, glucose, fructose, sedoheptulose.
