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.

所有这些身体部位大约 70% 是矿物质，由一种叫做羟基磷灰石无机材料制成，这种材料在压缩时是坚硬，与一种叫做胶蛋白柔性蛋白质在一起，可防止你粉碎。

It reacts with HOPDMS in such a way that it breaks off a hydroxyl group from one end of each chain, so that two chains can join together!

它与 HOPDMS 产生反应，通过打断每一个链接末尾羟基组，使得两个链接可在一起！

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%磷酸盐储存在骨骼中，它在骨骼与钙形成一种叫做羟基磷灰石坚硬化物，这是为什么骨头比较坚硬因。

Monosaccharides link together through glycosidic bonding, which is when an " OH" from the carbon on one monosaccharide bonds with an " H" from the carbon of another monosaccharide.

单糖之间通过糖苷键连接，即一个单糖分上羟基与另一个单糖分上氢缩。

Their experiments show that methanol, commonly known as wood alcohol, and hydroxyl react rapidly at –210 degrees Celsius to form methoxy, which has also been spotted in space.

他们实验显示，甲醇（俗名木精）和羟基形成甲氧基反应速度在零下 210 摄氏度时很快，而研究人员也在宇宙中发现了这一过程。

They found that it binds to chromatin, the compact structure that allows long molecules of DNA to ball up and fit into a tiny cell.

研究人员认为，Dsup作为一种染色质绝缘体，可保护DNA免受羟基自由基攻击。

Within bones, calcius is found primarily as hydroxy appetite, and is bound the collagen within bones.

在骨骼中，钙质主要作为羟基食欲，并与骨骼中胶蛋白。

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磷灰石矿物形成。

And I started popping hydroxycut diet pills, the ones that had raw ephedrine in them.

我开始服用含有麻黄碱羟基切割减肥药。

If it's a six carbon chain with a carboxylic acid on it and an alcohol on one of the other carbons, our name has to do two things: identify that the hydroxyl group is there and identify where it is.

如果它是一个六链， 上面有一个羧酸， 另一个上有一个醇，我们名字必须做两件事：确定羟基存在并确定它位置。

It is not that HIF1 alpha is being oxidized and thus destroyed rather the hydroxyl groups which are created by a reaction between HIF1 alpha and oxygen market for destruction by a cell's protein degrading machinery The practical upshot of all.

并不是HIF1α被氧化并因此被破坏，而是HIF1α与氧气反应生成羟基标记了其会被细胞蛋白质降解机器破坏。总之，实际果是这样。

If you were paying attention, you learned that alcohols are organic compounds with hydroxyl groups, if you dehydrogenate them, the hydroxyl converts to a carbonyl and they become dehydrogenated alcohols or aldehydes.

如果你注意听了，你应该知道醇是含有羟基有机化物， 如果你对其进行脱氢处理， 羟基会转化为羰基， 从而变成脱氢醇或醛。

In the second step, the L-dopa formed by tyrosine hydroxylation is quickly decarboxylated by another enzyme called aromatic L-amino acid decarboxylase (AADC), to the neurotransmitter dopamine.

在第二步中，由酪氨酸羟基化形成L-多巴通过酶快速脱羧另一种称为芳香族L-氨基酸脱羧酶（AADC）神经递质多巴胺。

THAT was the sound of 2-hydroxybenzaldehyde.

那是2-羟基苯甲醛声音。

But that discordant nightmare was an audible soundscape that represents the chemical properties of 2-hydroxybenzaldehyde.

但那不和谐噩梦是一个可听见声音景观，代表了2-羟基苯甲醛化学性质。

He showed that VHL and HIF-1 alpha interact with one another and that this interaction which incorporates molecules called hydroxyl groups into the mix makes HIF1 alpha susceptible to degradation in the presence of oxygen.

他证明了VHL和HIF-1α相互作用，并且这种包含羟基分交互使得HIF-1α在有氧条件下容易被降解。

Sometimes a hydroxyl group from one molecule is happy to join up with a hydrogen from another, forming water.

有时，一个分中羟基很乐意与另一个分中氢， 形成水。

For example if we have a carbonyl bonded to a Hydroxyl, that, my friends, is a Carboxylic Acid.

例如，如果我们有一个与羟基键羰基，那，我朋友们， 就是一个羧酸。
