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

种矿物质大部羟磷灰石——它们非常坚硬且富含钙质和磷酸盐。

The lamellae have an organic part, which is mostly collagen, and an inorganic part called hydroxyapatite, which is mostly calcium phosphate.

片的有机部主要胶原蛋白，无机部称为羟磷灰石，其主要磷酸钙。

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

大约99%的钙在我们的骨骼中以磷酸钙的形式存在，也被叫做羟基磷灰石。

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.

所有身体部位大约 70% 矿物质，由一种叫做羟基磷灰石的无机材料制，种材料在压缩时坚硬的，与一种叫做胶原蛋白的柔性蛋白质结合在一起，可以防止你粉碎。

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.

在人体中，约85%的磷酸盐储存在骨骼中，它在骨骼与钙结合形一种叫做羟基磷灰石的坚硬化合物，为什么骨头比较坚硬的原因。

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

种矿物主要羟基磷灰石 - - 一种富含钙和磷酸盐的坚硬物质。
