Simple sugars are referred to as what due to their chemical structure?

• A. Disaccharides
• B. Monosaccharides
• C. Polysaccharides
• D. Oligosaccharides

Answer: (B)

Simple sugars are referred to as monosaccharides because mono- means one, and these molecules consist of a single sugar unit. They are the smallest, most basic building blocks of carbohydrates, which is why they’re called monosaccharides. Glucose, fructose, and galactose are common examples. In solution they can switch between straight-chain and ring forms, but the crucial point is that they cannot be broken down into smaller sugar units. When two sugar units are linked together, the result is a disaccharide; several or many units form oligosaccharides or polysaccharides, respectively. So the term monosaccharide specifically identifies the one-unit nature of these simple sugars.
