What enzyme is known to be derived from animals?

The correct answer is pancreatin, which is known to be derived from animals, specifically from the pancreas of pigs or cattle. Pancreatin is a mixture of digestive enzymes, including amylase, protease, and lipase, which are essential for breaking down carbohydrates, proteins, and fats in the digestive system. Its animal origin makes it distinctive compared to other enzymes, which can be derived from both animal and plant sources.

Amylase, lactase, and protease can be found in various forms and originate from different sources. While some amylases and proteases are also derived from animals, they can also be produced by plants and microorganisms. Lactase, which breaks down lactose, is typically produced in mammals and can be derived from other sources, but it is not primarily associated with animal-sourced products like pancreatin. Therefore, pancreatin is specifically notable for its animal-based derivation, setting it apart in this context.
