Fig. 5From: Binding interaction of sodium benzoate food additive with bovine serum albumin: multi-spectroscopy and molecular docking studiesThe UV–Vis absorption spectra of BSA in the absence and presence of different concentrations of SB. The BSA concentration was 1.0 × 10−6 M; while the SB concentration increased from 0 to 8.0 × 10−6 M, with a step size of 2.0 × 10−6 M from a to fBack to article page
