Question

What is the main carbohydrate found in cow's milk?

• A. Glucose
• B. Fructose
• C. Lactose
• D. Sucrose

Hint:

People with lactose intolerance lack the enzyme lactase, which is needed to digest lactose properly.

Answer 1

The Correct Option is C

Concept: Milk contains several nutrients including proteins, fats, vitamins, minerals, and carbohydrates. The primary carbohydrate present in milk is lactose, also known as milk sugar. Lactose is a disaccharide composed of:

• Glucose
• Galactose

It plays an important role in:

• Providing energy
• Supporting growth of beneficial gut bacteria
• Contributing to the taste of milk

Step 1: Identify carbohydrates in milk.
Unlike fruits (which contain fructose) or table sugar (sucrose), milk uniquely contains lactose.
Step 2: Analyze the options.

• Glucose – simple sugar, not the main milk carbohydrate
• Fructose – fruit sugar
• Lactose – milk sugar (correct)
• Sucrose – table sugar

Step 3: Select the correct answer.
Thus, lactose is the main carbohydrate found in cow’s milk.
