additional information | the inhibitory activity of the flavonoids toward human alpha-amylase depends on the formation of 1. hydrogen bonds between the hydroxyl groups in position R7 and/or R4' of the polyphenol ligands and the catalytic residues of the binding site Asp197 and Glu233 and 2. formation of a conjugated pi-system between either the AC- or B-ring system and Trp59, that stabilizes the interaction with the active site | Homo sapiens | |
