Keratin/galactose and sucrose comprised of the mixture structure of [alpha]-helix and random coil deformation while the structure of keratin/starch blend film was [alpha]-helix mixed [beta]-sheet structure.
One can speculate from the data presented here, however, that synthetic NT-proBNP is likely an unordered random coil with an extended-like structure.
At high shear rates, the time allowed for the formation and dissolution of entanglements is very short since the interaction time for two molecules whose random coil dimensions are overlapped is brief.
WAXD and FTIR results confirmed that the crystal structure of SF was not influenced by adding the different contents of SA, exhibiting the random coil structure in the hybrid scaffolds.
Conformational transition of SF from random coil to [beta]-sheet form can perform by heat treatment, alcohol treatment, polymer blending and cross-linking [7-9].
The molecule chains of random coil configuration had a stronger damping effect than that of extending orientation configu-ration.

Flexible chain polymers like PET are characterized by a random coil conformation in the quiescent melt or solution.
Orientation can be built into random coil polymers by stretching at proper temperatures in secondary processes to initial forming [4], whereas a great deal of orientation is built into LCPs at the time of primary extrusion or molding.
