History
The term "pepsin" was first coined by Theodor Schwann in the early 19th century. Scientists around this time began discovering many biochemical compounds that play a significant role in biological processes and pepsin was one of them. It was with the identification of a chemical agent found in the stomachs of animals, that scientists began looking into the digestive properties of organisms. This acidic substance that was able to convert nitrogen based foods into water soluble material was determined to be pepsin.
