Effect of Restricted Conformational Flexibility on the Permeation of Model Hexapeptides Across Caco-2 Cell Monolayers

Abstract
Purpose. To determine how restricted conformational flexibility of hexapeptides influences their cellular permeation characteristics. Methods. Linear (Ac-Trp-Ala-Gly-Gly-X-Ala-NH2; X = Asp, Asn, Lys)...
