Question

2 — digestion and absorption of lipids
learning objective: define the process of digestion and absorption of lipids in our body.
which enzymes break down triacylglycerols into fatty acids and diglycerides?

a.) lecithin
b.) lingual lipase
c.) salivary amylase
d.) gastric lipase

Explanation:

• Option a: Lecithin is a phospholipid, not an enzyme, so it can't break down triacylglycerols.
• Option b: Lingual lipase (secreted in the mouth) and Option d: Gastric lipase (secreted in the stomach) are enzymes that catalyze the breakdown of triacylglycerols into fatty acids and diglycerides.
• Option c: Salivary amylase breaks down starch (carbohydrates), not lipids.

Answer:

b.) Lingual lipase, d.) Gastric lipase
