trypsin etymology

Etymology and Meaning of Trypsin

Etymology:

Trypsin derives its name from two Greek words:

• "trypsin" (τρύω) - meaning "to rub" or "to grind"
• "pepsin" (πέψις) - meaning "digestion"

Meaning:

Trypsin is an enzyme that breaks down proteins into smaller peptides. Its name reflects its function of rubbing (digesting) proteins to facilitate their absorption.

Origin

Trypsin was first discovered and isolated in 1879 by German physiologist William Kühne. He extracted trypsin from the pancreatic juice of dogs and found that it had proteolytic activity.

Kühne proposed the name "trypsin" to describe this enzyme because it was associated with the process of digestion (pepsin), and it acted by rubbing or grinding down proteins.

Since Kühne's discovery, trypsin has been found in a wide variety of organisms, including humans, animals, and plants. It is a key enzyme in the digestive system and plays an important role in breaking down dietary proteins into absorbable peptides.
