Amylin Uncovered: A Review on the Polypeptide Responsible for Type II Diabetes
Figure 7
Diagram showing how (a) unmodified amino acids can form β-sheet structures via hydrogen bonding (represented as - - -) and how (b) N-methylation (expressed as dark circles) replaces hydrogen in a polypeptide and thus preventing β-sheet stacking. R1–R4 represent the side groups of the amino acids. Adapted from Rijkers et al. [116].
