Pathway Selection in Peptide Amphiphile Assembly

Korevaar, Peter A., Newcomb, Christina J., Meijer, E. W., Stupp, Samuel I.·2014·Journal of the American Chemical Society

Abstract

The nature of supramolecular structures could be strongly affected by the pathways followed during their formation just as mechanisms and final outcomes in chemical reactions vary with the conditions selected. So far this is a largely unexplored area of supramolecular chemistry. We demonstrate here how different preparation protocols to self-assemble peptide amphiphiles in water can result in the formation of different supramolecular morphologies, either long filaments containing β-sheets or smaller aggregrates containing peptide segments in random coil conformation. We found that the assembly rate into β-sheets decreases in the presence of a destabilizing "good" solvent like hexafluoroisopropanol (HFIP) and is affected by transient conditions in solution. Also the peptide amphiphile investigated spontaneously nucleates the β-sheet-containing filaments at a critical fraction of HFIP in water below 21%. Furthermore, β-sheet assemblies have a high kinetic stability and, once formed, do not disassemble rapidly. We foresee that insights into the characteristic dynamics of a supramolecular system provide an efficient approach to select the optimum assembly pathway necessary for function.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
