Question

Which of the following sugar is found in milk?

• A. Glucose
• B. Fructose
• C. Lactose
• D. Galactose
• E.

Hint:

Lactose = Galactose + Glucose. It's the primary sugar in milk.

Answer 1

The Correct Option is C

Step 1: Lactose Identification.
Lactose, a disaccharide comprising glucose and galactose, is the principal sugar present in milk. It serves as an energy source and facilitates calcium absorption.

Step 2: Evaluation of Alternatives.
- (1) Glucose: Incorrect. While present in numerous foodstuffs, glucose is not the predominant sugar in milk.
- (2) Fructose: Incorrect. Fructose is indigenous to fruits, not milk.
- (4) Galactose: Incorrect. Galactose is a constituent of lactose; however, it is not found independently in milk.

Step 3: Determination.
Consequently, option (3) Lactose is the accurate selection, being the primary sugar in milk.
