Two prolines with a difference: contrasting stereoelectronic effects of 4R/S-aminoproline on triplex stability in collagen peptides [pro(X)-pro(Y)-Gly]n.
4R/S-Aminoprolines when present in the X-position of collagen peptide [pro(X)-pro(Y)-Gly]n exhibit pH- and stereochemistry-dependent effects on triplex stability.
