CaCO3 Crystals with Unique Morphologies Controlled by the Hydrogen-Bonded Supramolecular Assemblies of Ureido-Pyrimidinone-Amino Acid Derivatives

Abstract: Biomineral materials such as nacre of shells exhibit high mechanical strength and toughness on account of their unique “brick-mortar” multilayer structure. 2-Ureido-4­[1H]-pyrimidinone (UPy) derivatives with different types of end groups, due to the self-complementary quadruple hydrogen bonds and abundant Ca2+ binding sites, can easily self-assemble into supramolecular aggregates and act as templates and skeleton in the process of inducing mineral crystallization. In this work, UPy derivatives were used as tem… Show more

“…Invertebrate organisms develop hard mineral structures for various functions such as mechanical support and protection from predators. , Calcium carbonate (CaCO 3 ) is a common biomineral found in the shells of numerous invertebrates, including crustaceans, echinoderms, and mollusks. Different polymorphs of CaCO 3 , such as crystalline calcite, vaterite, aragonite, and amorphous calcium carbonate (ACC) exist in nature Among these polymorphs, calcite and aragonite crystals are the biologically abundant polymorphs of CaCO 3 . The polymorph selectivity is achieved in the presence of proteins or environmental conditions, for example, magnesium (Mg) ions in saltwater induce selective nucleation of aragonite crystals. , …”

“…Biomolecules such as peptides, proteoglycans, or other acidic macromolecules facilitate and control the biomineralization processes. Biomineral composites usually contain a small percentage (<5%) of the organic materials inside the dense mineral phase . Aragonite needles are organized to provide excellent mechanical properties and a defect-free architecture for the mollusk shells. A few research groups have tried to understand the molecular mechanism of biomineralization by isolating and studying the soluble organic materials (SOMs) from diverse mineralized tissues and evaluating their in vitro activities. The biomineralization of eggshells and a few seashells were studied extensively and active peptides were isolated and fully characterized. , …”
