What does lipase specifically break down?

• A. Triglycerides into fatty acids and glycerol
• B. Starch into glucose
• C. Protein into amino acids
• D. Lactate into pyruvate

Answer: (A)

Lipase is an enzyme that plays a crucial role in the digestion of fats, specifically targeting triglycerides. Its primary function is to catalyze the hydrolysis of triglycerides, breaking them down into fatty acids and glycerol. This process is vital for lipid metabolism, allowing the body to utilize fats as a source of energy or store them for future use.

Additionally, lipase is secreted by the pancreas into the small intestine, where it operates optimally in the presence of bile salts, which emulsify fats and enhance lipase activity. The products of this enzymatic reaction—fatty acids and glycerol—are then absorbed by the intestinal lining and transported throughout the body for various metabolic processes.

The other options pertain to different enzymes known for distinct biochemical functions: starch is broken down by amylase, proteins are degraded by proteases, and lactate is converted into pyruvate by lactate dehydrogenase. Each of these enzymes has a specific substrate and action that does not overlap with lipase’s function of hydrolyzing triglycerides.
