(A) Circular dichroism spectra of the free CA in H2O, the entrapped CA in 20% HOOC-FMS, and the released CA from 20% HOOC-FMS in H2O at 25 °C, where the baseline of the corresponding control sample (H2O or FMS in H20) was substracted. The released CA was prepared by first allowing CA released from FMS in pH 8.3, Tris-H2SO4 buffer, then dialysised in H2O. [CA]: 0.07 mg/mL in H2O. The specific activity of the free CA in H2O was 3583.3 units/mg, while that of the released CA from HOOC-FMS was 3425.6 units/mg; (B) Deconvolution results of CD spectra of CA and CA in 20% HOOC-FMS. Software used is CDNN 2.1. Analysis is based on CD spectra in the range of 200–260 nm.
