Condensed tannin (CT) interactions study with BSA by circular dichroism (CD).

<p>(A) Normalised CD spectra from qBiC software of BSA (reference in dark blue) and of BSA upon interactions with CT fractions (see legend in B); (B) CD difference spectrum of BSA treated with CT fractions calculated by subtracting the ‘CT only’ CD spectra (CD<sub>CT</sub>) and the ‘BSA only’ CD spectra (CD<sub>BSA</sub>) from the spectrum recorded with the CT and BSA mix (CD<sub>BSA_CT</sub>): ΔCD = CD<sub>BSA_CT</sub> - (CD<sub>CT</sub> + CD<sub>BSA</sub>).</p>
