Proteins play important roles in the process of biomineralization. Vaterite and calcite have been synthesized by the reaction of Na2CO3 and CaCl2 in the bovine serum albumin (BSA) and agar system. The samples have been characterized by Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). The shape of CaCO3 crystal has been analyzed by scanning electronic microscopy (SEM). The results show that calcite is a single product in the absence of BSA, but the product is a mixture of calcite and vaterite in the presence of BSA. The spheral shell of CaCO3 crystal was obtained when the concentration of BSA increased to 9.0mg/mL.
蛋白质在生物矿化过程中起着重要作用。牛血清白蛋白（BSA）和琼脂体系中，通过 Na2CO3 和 CaCl2 的反应合成了文石和方解石。样品通过傅里叶变换红外光谱（FT-IR）和 X 射线衍射（XRD）进行了表征。通过扫描电子显微镜（SEM）分析了 CaCO3 晶体的形状。结果表明，在没有 BSA 的情况下，方解石是唯一的产物，但在有 BSA 的情况下，产物是方解石和文石的混合物。当 BSA 的浓度增加到 9.0mg/mL 时，得到了 CaCO3 晶体的球形外壳。
