Abstract
The intracellular pH of the shell gland of the domestic fowl was calculated at various stages in egg-shell formation. The calculation is based on the distribution of 5,5-dimethyloxazolidine-2,4-dione between intracellular and extracellular water. The results show a rapid fall in intracellular pH at the time of mineralization and this is interpreted as indicating a removal of protons from the site of calcification.
摘要
在家禽蛋壳形成的不同阶段，计算了蛋壳腺细胞内的pH值。该计算基于5,5 - 二甲基恶唑烷 - 2,4 - 二酮在细胞内和细胞外水之间的分布。结果显示，在矿化时细胞内pH值迅速下降，这被解释为表明质子从钙化部位被移除。
