“The pH of the buffer solution and captopril– HSA interaction may play more important roles in transforming the secondary structure of HSA from α-helix to β-sheet in the corresponding captopril–HSA mixture than UV-B exposure.”
“There was little disulfide formation in the captopril–HSA mixture even with long-term UV-B exposure, but captopril might interact with HSA to change the protein secondary structure of HSA whether there was UV-B irradiation or not.”
