Question

What is the Shrinkage temperature of native collagen fibers in skin?

• A. ( ∼ 60^circ C )
• B. ( ∼ 37^circ C )
• C. ( ∼ 90^circ C )
• D. ( ∼ 120^circ C )

Hint:

Collagen's shrinkage temperature (( sim 60^circ C )) is an important parameter in leather technology, as it influences the processing conditions and material properties of collagen-based products.

Answer 1

The Correct Option is A

The shrinkage temperature of native collagen fibers, particularly in skin, is around 60°C. At this temperature, collagen begins to undergo irreversible changes, including the denaturation of the triple-helix structure. This marks the transition of collagen from a functional biomolecule to a structurally weakened form. Key Insights: - At ( sim 60^circ C ), collagen fibers lose their natural integrity, which is significant in leather processing and other industries involving collagen-based materials. - The shrinkage temperature is crucial in understanding collagen's behavior in various biological and industrial applications.
