Many mineralizing organisms selectively form either calcite or aragonite, two polymorphs of
calcium carbonate with very similar crystalline structures. Understanding how these …

The growth of molluscan shell crystals is usually thought to be initiated from solution by
extracellular organic matrix. We report a class of granulocytic hemocytes that may be directly …

IN the initial stages of the biomineralization of abalone shells, a primer layer of oriented
calcite crystals grows on a nucleating protein sheet1, 2. The deposition of this primer is …

The extrapallial fluid (EPF), the fluid component of the shell-forming system of molluscs, has
been examined for its effect on the rate of CaCO3 crystal formation in vitro. The medium was …

The microarchitecture of gastropod nacre reveals deposition of aragonite in the form of
crystal stacks and differs markedly from the characteristic microstructure of pelecypod nacre …

The hydrophilic, sulfated fraction of the organic matrix found in molluscan shells appears to
be involved in crystal nucleation. It is located primarily at the sites of initial nucleation. The …

The organic matrix of calcium carbonate structures can be involved in the formation of the
biomineral by regulating various stages of crystal growth. The preponderance of evidence …

Normal biogenic calcium carbonate is deposited as calcite or aragonite with preferred
crystal orientation. The site of mineralization is isolated, and the parent medium may have a …

The skeletons of adult echinoderms comprise large single crystals of calcite with smooth
convoluted fenestrated morphologies, raising many questions about how they form. By using …
