Which animal's insulin molecule is identical to that of the feline insulin?

Bovine
Porcine
Ovine
Human

The correct answer is: Bovine

The correct response is that the porcine (pig) insulin molecule is identical to feline insulin. In fact, porcine insulin is often used in veterinary medicine for diabetic cats due to its structural similarity. The amino acid sequence of porcine insulin closely aligns with that of feline insulin, making it an effective treatment choice. Bovine (cow) insulin has a slightly different structure as it contains one additional amino acid compared to human insulin. Ovine (sheep) insulin also differs from feline insulin, as do other species' insulins. While human insulin shares a significant similarity with feline insulin, it is not identical. Hence, the best choice for identical insulin structure in this context is porcine insulin.
