钙是人体内含量最多的矿物质成份,绝大部分钙都储存在骨组织中,骨钙量约占人体钙总量的90%以上。正常情况下,骨钙中约99%的钙是相对稳定的,称为稳定性钙;约1%的骨钙可与细胞外液交换,称为可溶合钙(Misciblecalcium)。软组织钙、细胞外液钙和可溶合钙合称为不稳定钙。稳定性
Calcium is the most abundant mineral in the human body. Most of the calcium is stored in the bone tissue, and the amount of bone calcium accounts for more than 90% of the total body calcium. Under normal circumstances, about 99% of calcium in bone calcium is relatively stable, known as the stability of calcium; about 1% of bone calcium can be exchanged with the extracellular fluid, called soluble calcium (Misciblecalcium). Soft tissue calcium, extracellular calcium and soluble calcium together called unstable calcium. stability
