The examples of disaccharides are
(A) Sucrose
(B) Maltose
(C) Lactose
(D) Cellulose
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A), (B) and (C) only
Carbohydrates are classified based on the number of monosaccharide units present.
Monosaccharides → Single sugar unit Example: Glucose, Fructose
Disaccharides → Two monosaccharide units joined by glycosidic bond
Polysaccharides → Many monosaccharide units
Disaccharides form by condensation of two monosaccharides with loss of one water molecule
(A) Sucrose Formed from: Glucose + Fructose It is a disaccharide linked by glycosidic bond. Hence correct.
(B) Maltose Formed from: Glucose + Glucose It is also a disaccharide. Hence correct.
(C) Lactose Formed from: Glucose + Galactose It is a disaccharide found in milk. Hence correct.
(D) Cellulose Formed from: Thousands of glucose units It is a structural polysaccharide present in plant cell walls. Not a disaccharide.
HENCE, The correct answer is Option (1) → (A), (B) and (C) only
