Inside Cover: Phase Selection of Calcium Carbonate through the Chirality of Adsorbed Amino Acids (Angew. Chem. Int. Ed. 29/2007)
Chiral crystallization additives can determine the phase selection of calcium carbonate. W. Tremel and co-workers show this phenomenon in their Communication on page 5618 ff. for d and l amino acids, which adsorb chiroselectively on the surface of terraced calcite surfaces. Conversely, calcite may serve as a template during the formation of homochiral amino acids from racemic precursors.
