The study of interactions between peptides and synthetic polymers has aroused considerable interest recently.In the present paper,the interaction mechanism between adsorbent DMAPAM and two pep-tides,VVRGCTWW(V8)and CTWW(C4),was investigated at molecular level by NMR and molecular stimulation.The results demonstrated that the conformation of oligopeptides played a vital role in their adsorption capacity on the adsorbent.Weak interactions could incorporate with each other between V8 and DMAPAM because there was a hydrophobic cleavage in α-helix conformation of V8.So the ad-sorption capacity of DMAPAM to V8 was higher.This was significant to explore the interaction mecha-nism between peptides and biomaterials.
