Detailed explanation-1: -Sucrose is not an example of polysaccharides.
Detailed explanation-2: -Lactose is a disaccharide comprised of glucose linked to galactose. Disaccharides are sugars made of two carbohydrate residues. Lactose is therefore not a polysaccharide because the biochemical definition of a polysaccharide states that polysaccharides must possess at least three carbohydrate residues linked together.
Detailed explanation-3: -Answer and Explanation: The correct answer is D). Chitin, glycogen, and cellulose are all polysaccharides. However, Lipids are not polysaccharides.
Detailed explanation-4: -Glucose, galactose, and fructose are common monosaccharides, whereas common disaccharides include lactose, maltose, and sucrose. Starch and glycogen, examples of polysaccharides, are the storage forms of glucose in plants and animals, respectively. The long polysaccharide chains may be branched or unbranched.
Detailed explanation-5: -Lactose is glucose-and galactose-forming disaccharide.
