_______ are used in detergent formulations and are helpful in removing oily stains from laundry.
1)Ligases
2) Proteases
3) Lipases
4)Pectinases

Options

A. Ligases
B. Proteases
C. Lipases
D. Pectinases

Answer

To solve the question about which enzyme is used in detergent formulations to help remove oily stains from laundry, we will analyze each option provided:

1. **Ligases**:
- Ligases are enzymes that are primarily involved in molecular biotechnology. They are responsible for joining fragments of DNA or RNA. Since their function is related to genetic material and not to breaking down oils or fats, they cannot be the answer.

2. **Proteases**:
- Proteases are enzymes that break down proteins. While they are useful in various applications, including digestion, they do not target fats or oils. Therefore, they are not suitable for removing oily stains.

3. **Lipases**:
- Lipases are enzymes that specifically break down fats and lipids. Since oily stains are primarily composed of fats, lipases are effective in digesting these oils, making them suitable for use in detergent formulations aimed at removing oily stains from laundry.

4. **Pectinases**:
- Pectinases are enzymes that break down pectin, a polysaccharide found in plant cell walls. They do not act on fats or oils, so they cannot be the answer to this question.

Based on the analysis of the functions of these enzymes, the correct answer to the question is:

**3) Lipases**
