Ferritin is a cage-like carrier protein with multiple interfaces, allowing the encapsulation and delivery of biologically active molecules. In this study, hesperetin was covalently conjugated to the outer surface of ferritin to fabricate hesperetin-covalently modified ferritin (HFRT) at pH 9.0. This conjugation resulted in a binding equivalent of hesperetin to ferritin of 12.33±0.56 nmol/mg. After covalent binding, the free amino content of HFRT decreased, and the secondary and tertiary…
