含O-磷酸-L-丝氨酸[Ser（P）]的多肽和蛋白质在控制生物矿物的形态中起着重要作用。聚[Ser（P）]和共聚[Ser（P）（x）Asp（y）]影响碳酸钙（CaCO 3）的形态和多晶型。在[Ser（P）（75）Asp（25）]共聚物存在下，CaCO_3形成螺旋结构。当L-共聚物用作添加剂时，形成顺时针P扭转螺旋形态。另一方面，当使用D-共聚物时，获得逆时针M扭转螺旋形态。
The O-phospho-L-serine [Ser(P)] containing peptides and proteins play an important role in controlling the morphology of biominerals. The poly[Ser(P)] and copoly[Ser(P)(x)Asp(y)] affect the calcium carbonate (CaCO3) morphology and polymorph. The CaCO3 helical structures were obtained in the presence of copoly[Ser(P)(75)Asp(25)]. When the L-copolymer was used as an additive, a clockwise P twisted spiral morphology was formed. On the other hand, when using D-copolymer, a counterclockwise M twisted spiral morphology was obtained.
