The present invention relates to a chelated calcium ion calcium carrier, specifically to a calcium carrier composed of polyhydroxyalkanoate (PHA), wherein the carboxyl end of the PHA is located on the calcium side of the interior of the granular carrier, the hydroxy end of the PHA is located on the exterior thereof, and the PHA granule has a chelated calcium ions structure, thereby allowing the biodegradable PHA granule to be used for a variety of purposes needing storage, absorption, transport and removal of calcium by using the PHA granule as a storage/transport vehicle for calcium. |
