In many marine creatures, however, the skeleton is composed of a mineral variety of calcium carbonate called aragonite. Although aragonite has the same composition as the more familiar mineral known as calcite, it has a different crystal form, is relatively unstable, and in time changes to the more stable calcite.

Abstract: In this paper, the effect of hydroxyl groups on CaCO3 mineral phases and their interfacial energies in biological-like fluids (alcohol-water mixtures) were studied. The results show that polyhydroxy alcohols are beneficial to the formation of metastable vaterite, and the addition of alcohols can increase the interfacial energies between calcite and vaerite.
