The enzyme diastase is present in

Options

A. Wash
B. Wort
C. Malt
D. Yeast

Answer

To solve the question regarding the presence of the enzyme diastase, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Diastase**:
- Diastase is an enzyme that catalyzes the breakdown of starch into simpler sugars, primarily maltose. It is important to know the function of the enzyme to identify where it is found.

2. **Chemical Reaction**:
- The reaction catalyzed by diastase can be represented as:
\[ \text{Starch} \xrightarrow{\text{Diastase}} \text{Maltose} \]
- This reaction indicates that diastase is involved in the conversion of starch (a polysaccharide) into maltose (a disaccharide).

3. **Identifying the Source**:
- Maltose is commonly derived from malt, which is produced from grains, particularly barley. The process of malting involves soaking grains in water to allow them to germinate, and then drying them to stop the germination process.

4. **Conclusion**:
- Since diastase is used in the malting process to convert starch in grains to maltose, we can conclude that diastase is present in malt. Therefore, the answer to the question is:
- **Diastase is present in malt.**

### Final Answer:
- The enzyme diastase is present in **malt**.
