Carbon-13 and proton magnetic resonance studies are reported on the interaction of calcium ions with a hexapeptide that is a repeating sequence in elastin . Of the seven carbonyls in N-formyl-L-Val-L-Ala-L-Pro-Gly-L-Val-Gly-OMe, six are observed to titrate downfield on sequential CaC1 : addition . D

## Abstract The interaction of calcium ions with α‐elastin has been investigated by equilibrium dialysis, CD, and microcalorimetric techniques. Consistent with literature data, it was found that the interaction in water is very poor. In trifluoroethanol (TFE), equilibrium dialysis experiments showe
