Trends for isolated amino acids and dipeptides: Conformation, divalent ion binding, and remarkable similarity of binding to calcium and lead

Matti Ropo, Volker Blum, Carsten Baldauf

We derive structural and binding energy trends for twenty amino acids, their dipeptides, and their interactions with the divalent cations Ca${}^{2+}$, Ba${}^{2+}$, Sr${}^{2+}$, Cd${}^{2+}$…
