pH and calcium concentration changes in a molluscan egg during development.
Abstract
During development, the egg albumen of calcified land snail eggs becomes more and more acid, correlated directly with a constant rise in the calcium concentration of this albumen. It is suggested that the developing embryo releases some acid metabolite and the subsequent change in albumen pH aids in embryonic absorption of the CaCO3 (calcite) egg shell, used for making the embryonic body shell or skeleton (CaCO3 in the form of aragonite).
