Which of the following statements is true about the suture material in the image?
Show Hint
Natural collagen suture from sheep or beef, digested by enzymes.
Updated On: Jun 24, 2026
- Made of rabbit submucosa
- Made of cat submucosa
- Not degraded
- Degraded by enzymatic degradation
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: The pictured suture is the classic natural absorbable thread known as catgut.
Step 2: Its real source is the collagen-rich submucosa of sheep intestine or the serosa of cattle, not the gut of a cat or a rabbit.
Step 3: Because it is animal collagen, the body removes it through proteolytic enzymes that digest the protein at the wound site, so it disappears by enzymatic breakdown rather than hydrolysis.
Step 4: Hence the correct statement is that the material is degraded by enzymatic degradation.
\[\boxed{\text{Degraded by enzymatic degradation}}\]
