Inhibition by glycosaminoglycans of CaCO3 (calcite) crystallization.
نویسندگان
چکیده
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.

Influence of conducting polymers based on carboxylated polyaniline on in vitro CaCO3 crystallization.
Conducting polymers are interesting materials of technological applications, while the use of polymers as additives controlling crystal nucleation and growth is a fast growing research field. In the present article, we make a first step in combining both topics and report the effect of conducting polymer derivatives, which are based on carboxylated polyanilines (c-PANIs), on in vitro CaCO3 crys...
متن کاملAssembly Synthesis of Sheet-like Calcite Array and Stable- Vaterite by Supported Liquid Membrane
CaCO3 can crystallize as calcite, aragonite and vaterite. Calcite and aragonite are the most common biologically formed CaCO3 polymorphs, and vaterite is transformed into calcite via a solvent mediated process. Calcium carbonate makes an attractive model mineral for studies, since the morphology of CaCO3 has been the subject to control in biomineralization processes. And control of vaterite als...
متن کاملInfluence of Cell-free Proteins in the Nucleation of CaCO3 Crystals in Calcified Endoskeleton
Calcite and aragonite are the two common polymorphs of CaCO3 observed as biominerals. It is universal that the sea water contents a high Mg (50mM) relative to Ca (10mM). In vivo crystallization, Mg inhibits calcite formation. For this reason, stony corals skeleton may be formed only aragonite crystals in the biocalcification. It is special in case of soft corals of which formed only calcite cry...
متن کاملA systematic examination of the morphogenesis of calcium carbonate in the presence of a double-hydrophilic block copolymer.
In this paper, a systematic study of the influence of various experimental parameters on the morphology and size of CaCO3 crystals after room-temperature crystallization from water in the presence of poly(ethylene glycol)-block-poly(methacrylic acid) (PEG-b-PMAA) is presented. The pH of the solution, the block copolymer concentration, and the ratio [polymer]/[CaCO3] turned out to be important p...
متن کاملWell-defined star-shaped calcite crystals formed in agarose gels.
Single crystals of calcite exhibiting a morphology of well-defined 8-armed stars, which evolved from original rhombohedral calcite crystals with their 8 points extending radially into eight arms, were produced by crystallization of CaCO3 in agarose gels.
