Anyways, about 99% of that calcium is in our bones in the form of calcium phosphate, also called hydroxyapatite.

99%的钙在我们的骨骼以磷酸钙的形式存在，也被叫做羟基磷灰石。

But others pointed out that the fossils were made from a mineral called hydroxylapatite.

但其他指出，这些化石是由一叫做羟基磷灰石的矿物形成的。

This mineral is mostly hydroxyapatite – tough stuff that's rich in calcium and phosphate.

这矿物主要是羟基磷灰石 - - 一富含钙和磷酸盐的坚硬物质。

In the body, about 85% of the phosphate is stored in the bones, where it combines with calcium to make a tough compound called hydroxyapatite which is the stuff that makes bones hard.

在，85%的磷酸盐储存在骨骼，它在骨骼与钙结合形成一叫做羟基磷灰石的坚硬化合物，这是为什么骨头比较坚硬的原因。

All of this from body parts that are about 70% mineral, made of an inorganic material called hydroxyapatite that is stiff when compressed, combined with flexible protein called collagen to keep you from shattering.

所有这些身部位 70% 是矿物质，由一叫做羟基磷灰石的无机材料制成，这材料在压缩时是坚硬的，与一叫做胶原蛋白的柔性蛋白质结合在一起，可以防止你粉碎。
