Calcium carbonates in gallstones
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 Relevance of the research. Сalcium carbonate, in the form of its three polymorphs: calcite, aragonite and vaterite, is included, beside natural systems, in composition of pathogenic biomineral aggregates, such as gallstones.

Calcium Carbonate Mineralization of Microalgae
Biomimetics, 2022 Biological substrates catalyze the nucleation and growth of sparingly soluble salts however, the underlying mechanism is largely unknown. In the present study, the growth of calcium carbonate (CaCO3), on Acutodesmus obliquus (AO) microalgae was investigated.

Carbon isotope fractionation between amorphous calcium carbonate and calcite in earthworm-produced calcium carbonate [PDF]
Applied Geochemistry, 2017 In this study we investigate carbon isotope fractionation during the crystallization of biogenic calcium carbonate. Several species of earthworm including Lumbricus terrestris secrete CaCO3. Initially a milky fluid comprising micro-spherules of amorphous CaCO3 (ACC) is secreted into pouches of the earthworm calciferous gland.

Calcium Carbonate Suppresses Haem Toxicity Markers without Calcium Phosphate Side Effect on Colon Carcinogenesis [PDF]
, 2010 Red meat intake is associated with increased risk of colorectal cancer. We have previously shown that haemin, haemoglobin and red meat promote carcinogen-induced preneoplastic lesions, aberrant crypt foci, in the colon of rats.
