trypsin
C1/C2 (Technical/Academic)Technical, Scientific, Medical
Definition
Meaning
A pancreatic digestive enzyme that breaks down proteins by cleaving peptide bonds.
A key enzyme used in biochemical research for protein digestion, cell culture, and tissue dissociation.
Linguistics
Semantic Notes

Memory Aids
Mnemonic
Think of 'TRYPSIN' as the enzyme that 'TRIPS' up proteins by cutting them into pieces.
Conceptual Metaphor
A molecular pair of scissors.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'tripsin' (non-existent). The correct Russian translation is 'трипсин'.
- It is not a general term for 'enzyme' (фермент) but a specific one.
Common Mistakes
- Misspelling as 'trypsine' (adding an unnecessary 'e').
- Incorrect pronunciation with stress on the second syllable (e.g., /trɪpˈsɪn/).

FAQ
Frequently Asked Questions
No, trypsin is found in the digestive systems of many vertebrates. Bovine (cow) trypsin is commonly used in laboratory research.
It is the process of using trypsin to detach adherent cells from a culture surface, often as a step in splitting or passaging cell lines.
In the body, trypsin is initially produced as an inactive precursor (trypsinogen) to prevent it from digesting the pancreas itself. In the lab, it is handled with care as it can damage skin and mucous membranes.
Both are proteases. Pepsin works in the acidic environment of the stomach, while trypsin works in the alkaline environment of the small intestine.
