HUMAN NUTRITION

Detailed explanation-1: -So, the correct answer is ‘Monosaccharide’.

Detailed explanation-2: -The pentoses, ribose, deoxyribose, and ribitol are also monosaccharides but are not thought of as major sources of dietary energy. They are called “pentoses” because, unlike glucose, fructose, and galactose, they are comprised of a five-carbon backbone rather than a six-carbon backbone.

Detailed explanation-3: -Ribose is the pentose sugar present in RNA, with one oxygen atom attached to each carbon atom. Deoxyribose sugar is the pentose sugar found in DNA. The presence of the hydroxyl (-OH) group on the 2’ carbon of the ribose and its absence on the 2’ carbon of the deoxyribose is the difference between the two sugars.
