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: -A monosaccharide contains a skeleton, of carbon atoms. The minimum number of carbon atoms is three and it can go up to seven.

Detailed explanation-4: -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-5: -The simplest sugars are monosaccharides. 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.
