**Core Concept**
Colipase is an enzyme that plays a crucial role in the digestion of dietary fats. It is a pancreatic enzyme that acts in conjunction with another enzyme to facilitate the breakdown of triglycerides in the small intestine.

**Why the Correct Answer is Right**
Colipase acts with lipase to break down triglycerides into free fatty acids and monoglycerides. The combination of colipase and lipase ensures optimal digestion and absorption of fats in the small intestine. Colipase binds to the surface of dietary fats, positioning lipase in close proximity to the triglyceride molecule, thereby enhancing the lipolytic activity of lipase.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because colipase does not act with amylase to break down carbohydrates.
**Option B:** This option is incorrect because colipase does not act with trypsin to break down proteins.
**Option C:** This option is incorrect because colipase does not act with gastric amylase to break down carbohydrates in the stomach.

**Clinical Pearl / High-Yield Fact**
Colipase deficiency can lead to steatorrhea (excessive fat in the stool), a condition characterized by malabsorption of fats and fat-soluble vitamins. This highlights the importance of colipase in maintaining normal fat digestion and absorption.

**Correct Answer: C. Lipase**
