Which of the following is correct statement w.r.t. animal insulin?

Options

A. It is just as effective as human insulin over prolonged time
B. It does not elicit immune response ever
C. It can be orally administrated to diabetic people
D. It was extracted from pancreas of slaughtered cattle and pigs

Answer

To determine the correct statement regarding animal insulin, let's analyze the options step by step:

1. **Understanding Animal Insulin**:
- Animal insulin refers to insulin derived from animals, such as pigs (porcine insulin) or cows (bovine insulin).
- It is used to treat diabetes in humans when human insulin is not available.

2. **Evaluating the Options**:
- **Option 1**: "It was just as effective as human insulin over prolonged time."
- This statement is incorrect. While porcine insulin is similar to human insulin, there are slight differences in their amino acid sequences, which can affect their effectiveness.

- **Option 2**: "It does not elicit an immune response."
- This statement is also incorrect. Porcine insulin can elicit an immune response in humans, as it is recognized as a foreign substance by the human immune system.

- **Option 3**: "It can be orally administered to diabetic people."
- This statement is incorrect. Insulin is a peptide hormone, and if taken orally, it would be digested in the stomach by proteolytic enzymes like pepsin, rendering it ineffective. Insulin must be administered via injection.

- **Option 4**: "It was extracted from the pancreas of slaughtered cattle."
- This statement is correct. Animal insulin, particularly bovine insulin, is extracted from the pancreas of slaughtered cattle.

3. **Conclusion**:
- The correct statement regarding animal insulin is **Option 4**: "It was extracted from the pancreas of slaughtered cattle."
