The Correct Option is A

Solution and Explanation


Concept: Digestion of fats occurs mainly in the small intestine with the help of bile and pancreatic lipase.
• Bile salts emulsify fats into small droplets (increase surface area).
• Pancreatic lipase acts on emulsified fats.
• Lipase breaks triglycerides into:
• Fatty acids
• Monoglycerides

Step 1:
Understand fat digestion.
Triglycerides (fats) are hydrolysed by lipase enzyme.

Step 2:
Identify products.
Lipase breaks ester bonds, producing fatty acids and monoglycerides.

Step 3:
Analyze options.
• (A) Monoglycerides: Correct
• (B) Monosaccharides: Products of carbohydrate digestion
• (C) Disaccharides: Intermediate carbohydrates
• (D) Triglycerides: Substrate, not product

Step 4:
Conclusion.
Thus, the missing product is monoglycerides. Final Answer: Option (A)
