Biological Mineralization and Demineralization

normal and pathological mineralization in vertebrates but also with the interesting problems involved in the formation of in­ tracellular deposits of calcium oxalate in plants. Here cal­ cium carbonate and silica may also be involved in the mineral­ ization processes. Calcium carbonate is an important component in the formation of mollusc and avian shells. The observation that both calcite and ara...
