Calcium ion (as mineral substrate) (Ca²⁺ (for calcium ion))

Calcium is an essential mineral and inorganic ion that serves as the major structural substrate in bone, teeth, and biomineralized tissues, primarily in the form of calcium phosphate and calcium carbonate. In biological systems, calcium is critical for mineralization processes, cellular signaling, maintenance of cellular structure, enzyme function, and overall homeostasis. Calcium as a mineral substrate drives the assembly and stabilization of tissues such as bone and enamel by providing the inorganic scaffold required for structural integrity. In regenerative medicine and tissue engineering, calcium mineral substrates (especially calcium phosphate) are used to support bone regeneration, dentin repair, and enamel remineralization. While calcium itself is not a drug target (such as a receptor or enzyme), its homeostasis and signaling are therapeutically modulated in several disease states. Use of the term "calcium as mineral substrate" describes its role as an inorganic scaffolding material rather than a molecular target.
