The organic matrix of mollusc shells includes organic components soluble in aqueous solutions and constituents not soluble in water and organic solvents. The matrix components are regarded to be closely involved in biomineralization processes. The concept of an organic matrix depends on the hypothesis, that macromolecular organic constituents largely control the deposition of solid inorganic matter. The insoluble matrical fraction is composed of varying quantities of macromolecules, and its surface may be hydrophobic. The chemical structure of the insoluble matrix and its biological significance on the molecular level needs more elucidation, although studies on the secondary structure revealed in some cases antiparallel s-pleated sheet conformation. The soluble matrical fraction from molluscs consists primarily of sulfated, high molecular weight glycoproteins at least some of them selectively bind calcium. Among the soluble biopolymers of the matrix the enzymes polyphenol oxidases have been detected.
