Random coil is significantly overrepresented in +1, +2, +3, +4, and +5 positions (see Table 2).
This algorithm shows what state (pure
random coil or
random coil with 3/10 helix) is more probable for a given connecting bridge.

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.
The rest is sometimes classified as "
random coil," but generally, it is neither random nor coiled.
Specifically, the spectra of the bands of 1650~1660,1665~1680, and 1660~1665 [cm.sup.-1] ranges are, respectively, corresponding to [alpha]-helix, [beta]-sheet, and
random coil of the protein.
We found that the percentage of
random coil structures was positively correlated with PS and digestibility, possibly because this structure is strong and flexible and has fewer hydrogen bonds that can impede enzyme access, which allows proteins to be readily degraded.
This demonstrated SA components obviously existing in the SF/SA hybrid scaffolds, and the crystalline structure of SF was also mainly the
random coil structure.
Compared with the control, on the whole, CRL7 exhibited a decrease in [alpha]helix and an increase in [beta]-sheet, [beta]-turn, and
random coil (except for xylene and acetonitrile whose [beta]-sheet decreased).
The SF matrix consisted of two main conformations including
random coil (water-soluble) and [beta]-sheet (water-insoluble) forms [6].
