摘要:
In this study, the changes in functional properties and binding mechanisms at the molecular level of a non-covalent complex formed between sweet potato leaf polyphenols (SPLPs) and rice bran albumin (RBA) were investigated. Multi-spectral analysis indicated that SPLPs statically quenched the intrinsic fluorescence of RBA, and fitting to a double logarithmic equation revealed that hydrogen bonding constituted the primary driving force behind this interaction. Consequently, the conformational structure, microenvironment, and surface hydrophobicit...
