“…In an important pioneering study, Arias showed that eggshell mineralization begins with the nucleation of calcite crystals on a discrete organic aggregation termed ''mammillan'', a proteoglycan which contains oversulfated keratin sulfate [40]. Of note, the polysaccharide region of mammillan was seen to resemble PS3 (see above), which is also a sulfated polysaccharide, but without a protein core.…”

Abstract12-Amino-acid peptides with binding-selected sequences and random functional groups synthesize the same inorganic material. Bacteria use structured polymers as filaments of cytoskeletal protein and of polysaccharides in templating biominerals. Nucleation appears to be involved not only in crystal formation, but also in the formation of porous or amorphous inorganic material. A seed of one iron ion for an iron-oxide cluster could be obtained in the low-iron-state of an archeal ferritin crystal. Porous inorganic materials were described to grow out in huge channeled complexes of organic compounds or crystallized seawater. The evolutionary progress of biomineralization runs apparently in the development of complex, inorganic-organic hybrid materials, composites, which are often structured hierarchically. The mechanical properties of a mineral undergo a change by presence and partition of the organic material, the most prominent example being the human skeleton. In order to describe such a complex system, a mathematical procedure -the finite element analysis -was introduced with great success. This analysis is governed amazingly by only one physical quantity, force, together with the modulus of elasticity. The overwhelming extent of research into the mechanical properties of skeletons has resulted in the conclusion that the aim of biomineralization appears to be stability.

“…The proteins and proteoglucans [40] involved in the scaffold construction of the eggshell palisade and mammillary layers have been the subjects of intense investigation, with an initial proteomic analysis of the chicken eggshell having been reported in March 2006 [41] by Mann.…”

“…It is known that the inorganic crystallization mechanism is altered by specific interactions between chemical groups, such as -CO 2 H, -PO 3 H, -SO 3 H containing insoluble additives or functionalized networks as solid templates [5][6][7][8][9][10]. In this sense, calcium carbonate (CaCO 3 ) represents the most abundant biomineral in nature and it has considerable industrial interest.…”

Abstract:A phosphorylated chitin (Chi-P) derivative was synthesized and its chemical structure was verified with Fourier-transform infrared spectroscopy (FTIR), elemental analysis, and thermogravimetric techniques (TGA). The influence of Chi-P used as a solid template through in vitro electrocrystallization (EC) supported on an indium zinc oxide (ITO) surface on the growth of calcium carbonate (CaCO 3 ) was studied. CaCO 3 crystals through EC essays were also compared with crystals obtained with the gas diffusion (GD) method. Scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDS), chronopotentiometry, Raman, and powder X-ray diffractometry (XRD) characterized all resultant inorganic particles. Our findings revealed that the EC method selectively controlled the coexistence of truncate calcite and the metastable phase of vaterite. The crystals' morphology reflects the electrostatic interaction of phosphate moieties from Chi-P onto CaCO 3 crystals through both EC and GD crystallization methods. We believe that the EC method represents a viable electrochemical approach for studying different inorganic minerals and could be useful as an in vitro classical crystallization method for the design of advanced inorganic materials with desirable shapes and properties.

“…The role of organic components in the formation, structure and emplacement of mineral phases, as firstly shown in mollusc shells by Wada (1960), is a fundamental one (Weiner & Dove, 2003). Chemical studies, in particular that of sulphur-based components, are crucial in the understanding of such a role (Arias et al, 2004). XANES mapping at the S K-edge has provided fundamental information on this subject in relation to biomineral production in organisms secreting calcium carbonate skeletons such as corals and mollusks (Cuif et al, Correspondence to: Alberto Pérez-Huerta.…”

Characterization of the nature and distribution of organic components is crucial to understand shell formation in marine invertebrates. Although several techniques can provide detailed information at high spatial resolution, few of them are non-destructive and informative in a larger structural context. We explore the use of confocal laser scanning microscopy (CLSM) to obtain a better understanding of the distribution of organic components in calcitic shells of brachiopods focusing on perforations (punctae) across the shell. Resulting intensities and patterns of fluorescence correspond well with the distribution of polysaccharides and proteins as reported in previous histological and biochemical studies. Confocal laser microscopy is, therefore, a useful tool to be combined with other techniques to improve our knowledge of biomineral structures in marine invertebrates. © 2008 The Authors
