BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The most common monosaccharides provided by foods are glucose, fructose and galactose. Sweet foods such as honey and cane sugar are rich in monosaccharides, but a wide variety of other foods, such as dairy products, beans and fruit, also contain these simple sugars.

Detailed explanation-2: -Final answer: Sucrose is not a monosaccharide.

Detailed explanation-3: -The monosaccharide galactose does not occur alone in foods; it binds with glucose to form lactose (a disaccharide). Galactose differs from glucose only in that a hydroxyl (−OH) group faces in a different direction on the number four carbon (Figure 4.1.
