Pancreatic lipase acts upon-

Options

A. Glycogen
B. Triglycerides
C. Disacharides
D. Polypeptides

Answer

### Step-by-Step Solution:

1. **Understanding the Enzyme**: Pancreatic lipase is an enzyme produced by the pancreas that plays a crucial role in the digestion of fats.

2. **Identifying the Substrate**: The primary substrate that pancreatic lipase acts upon is triglycerides. Triglycerides are a type of fat or oil composed of glycerol and three fatty acid chains.

3. **Analyzing the Options**:
- **Option 1: Glycogen** - This is incorrect because glycogen is a carbohydrate and is not acted upon by lipase.
- **Option 2: Triglycerides** - This is correct as pancreatic lipase specifically catalyzes the breakdown of triglycerides into glycerol and free fatty acids.
- **Option 3: Disaccharides** - This is incorrect because disaccharides are carbohydrates and are digested by enzymes like amylase, not lipase.
- **Option 4: Polypeptides** - This is incorrect as polypeptides are proteins and are broken down by proteolytic enzymes such as pepsin and trypsin.

4. **Conclusion**: Based on the analysis, the correct answer is that pancreatic lipase acts upon triglycerides.

### Final Answer:
**Pancreatic lipase acts upon triglycerides.**
