And those leaves also started secreting acid fluids that could dissolve any incoming apatite, assisting phosphorus's absorption.

这些叶子也开始分泌性液体，可以溶解任何进入灰石，帮助吸收。

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

这种矿物质部分是羟灰石——它们非常坚硬而且富含钙质和。

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

而99%钙在我们骨骼中以钙形式存在，也被叫做羟基灰石。

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

但其他人指出，这些化石是由一种叫做羟基灰石矿物制成。

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

这些薄片有机部分主要是胶原蛋白，而无机部分称为羟灰石，其主要成分是钙。

It does this by stimulating osteoclasts, the cells that break bone down, to release hydrogen ions which dissolves the hard, mineralized hydroxyapatite.

甲状旁腺激素通过刺激破骨细胞来释放氢离子；破骨细胞是一种分解骨骼细胞，可溶解坚硬矿化羟基灰石。

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，85%储存在骨骼中，它在骨骼与钙结合形成一种叫做羟基灰石坚硬化合物，这是为什么骨头比较坚硬原因。

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.

所有这些身体部位 70% 是矿物质，由一种叫做羟基灰石无机材料制成，这种材料在压缩时是坚硬，与一种叫做胶原蛋白柔性蛋白质结合在一起，可以防止你粉碎。
