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 (CaCO 3 ) morphology and polymorph. The CaCO 3 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.Optical micrographs of chiral morphologies of CaCO 3 in the presence of a) L ‐copolymer and b) D ‐copolymer.
