Teeth manage both by having two layers: a hard external cap of enamel, made up almost entirely of a calcium phosphate, and beneath it, a tougher layer of dentin, partly formed from organic fibers that make it flexible.

外层由坚硬的牙釉包围，几乎完全由酸钙组成，牙釉之下，有一层更加强韧的牙本，由有机纤维组成，它们能够使牙齿强韧。

Like the calcium phosphate stones, struvite stones are dirty white and radiopaque under an X-ray.

同酸钙结石一样，鸟粪石是灰白色的，在X线片上是不透光的。

Bone actually largely consists of tiny crystals of calcium phosphate, and the goo is in fact a combination of the compound citrate and water.

实际上骨骼很大程度上是由细小的酸钙晶体组成的，而种胶状物是复合柠檬酸与水的混合物。

Tooth enamel is made mostly of calcium phosphate, and genes that code for proteins designed to bind to calcium were particularly busy.

牙釉主要是由酸钙构成的，因此编码与钙结合蛋白的基因特别忙碌。

These minerals form calcium phosphate, which crystallize on the cartilage framework, ultimately forming a bone matrix that's about one-third mineral, two-thirds protein.

些矿物形成酸钙，酸钙在软骨框架上结晶，最终形成骨基，大约三之一的矿物和三之二的蛋白。

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

些薄片的有机主要是胶原蛋白，而无机称为羟灰石，其主要成是酸钙。

When osteoblasts come in, they secrete a glue-like cocktail of collagen, as well as enzymes that absorb calcium, phosphate, and other minerals from the blood.

当成骨细胞进入时，它们泌胶原蛋白以及从血液中吸收钙、酸盐和其他矿物的酶。

Calcium oxalate crystals are more likely to form in acidic urine, whereas calcium phosphate crystals are more likely to form in alkaline urine.

草酸钙结晶易形成于酸性尿中，而酸钙结晶易形成于碱性尿中。

From your time in the womb until you're about 25, your osteoblasts keep laying down more collagen and more calcium phosphate, until your bones are fully grown and completely hardened.

从你在子宫里的时候到你大约 25 岁，你的成骨细胞不断泌更多的胶原蛋白和酸钙，直到你的骨骼完全生长和完全硬化。

Sometimes, instead of oxalate, the calcium binds a negatively charged phosphate group to form calcium phosphate stones, which are dirty white in color and alsop radiopaque on an Xray.

有时候，钙离子与带负电荷的酸基团结合而非草酸，形成的酸钙结石呈灰白色，也在x线片上显影。

When they get there, they secrete both a collagen-digesting enzyme, and an acidic hydrogen-ion mixture that dissolves the calcium phosphate, releasing its components back into the blood. This tear-down process is called resorption.

当它们到达那里时，它们会泌胶原蛋白消化酶和酸性氢离子混合物，溶解酸钙，将其成释放回血液中。种撕裂过程被称为吸收。

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

而大约99%的钙在我们的骨骼中以酸钙的形式存在，也被叫做羟基灰石。

The phosphate binds to the ionized calcium and forms calcium phosphate, making it insoluble and effectively decreasing the total amount in blood.

与钙离子结合形成酸钙，使其不溶于水，并大大减少血液中的总钙量。

Your bones are basically how you store the calcium, phosphate, and other minerals you need to keep neurons firing and muscles contracting.

你的骨骼基本上是你储存钙、酸盐和其他矿物的方式，些矿物是保持神经元放电和肌肉收缩所需的。

Less common kidney stones are made of calcium phosphate or uric acid.

不太常见的肾结石由酸钙或尿酸构成。
