## **Core Concept**
Lingual lipase is an enzyme involved in the digestion of fats. It is secreted by glands in the tongue and plays a role in the initial breakdown of triglycerides in the oral cavity.

## **Why the Correct Answer is Right**
The correct answer, **D. Von Ebner's glands**, is right because Von Ebner's glands, located in the tongue, are responsible for secreting lingual lipase. This enzyme starts the digestion of fats in the mouth by breaking down triglycerides into fatty acids and monoglycerides, although the majority of fat digestion occurs later in the small intestine.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it is not specified, making it impossible to evaluate.
- **Option B:** This option is incorrect because it is not specified, making it impossible to evaluate.
- **Option C:** This option is incorrect because it is not specified, making it impossible to evaluate.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that while lingual lipase does contribute to fat digestion, its role is minor compared to pancreatic lipase in the small intestine. However, in conditions where pancreatic lipase is deficient (like pancreatic insufficiency), the role of lingual lipase can become more significant.

## **Correct Answer:** D. Von Ebner's glands
