2 2. Amorphous calcium carbonate in biomineralisation The notion that many organisms produce amorphous minerals such as silica, calcium phosphate, or calcium carbonate (ACC) has a long history, but it was not until the late 1960s that the first transient amorphous phase was identified in chiton teeth9.

Biominéralisation — Wikipédia

Les crustacés ont un exosquelette qui contient du carbonate de calcium amorphe [16], [17]. Le carbonate de calcium amorphe est la forme la moins stable de carbonate de calcium. Cette instabilité est permise par l’inclusion de molécules phosphatées, comme le phosphophénolpyruvate et le 3-phosphoglycerate.
