網頁2009年12月31日 · Here, we integrate stereoelectronic and steric effects to preorganize a polypeptide chain. The result is the most stable known collagen triple helix, by far. We show by calorimetric analyses that the conferred hyperstability derives from entropy, as expected if the hyperstability is due to the proper preorganization of backbone torsion angles.
