Table 2. Correlations of the ELP Aggregate Size²⁶ and Surface Water Content to the Secondary Structures of ELP Seen in FT-IR Spectroscopy^a.

^a(A) Large aggregate sizes rely on an increase in β-turns from 1 to 3.5 h and switch to the 3(10)-helix from 6 to 12 h to maintain their stability, as shown by the green shaded boxes. (B) A decrease in water content from 1 to 3.5 h shows no positive moderate or strong correlations between secondary structures, but the decrease in water content positively affects the formation of type II β-turns and 3(10)-helixes from 6 to 12 h, as shown by the green shaded boxes.
