Inhibition by glycosaminoglycans of CaCO3 (calcite) crystallization [PDF]
Biochemical Journal, 1989 Of a range of glycosaminoglycans, heparin and heparan sulphate were the most effective inhibitors in vitro of CaCO3 (calcite) crystallization as assayed by conductimetric measurements. The possible role of such glycosaminoglycans in modulating calcium-salt crystallizations in vivo is discussed.
