Then it starts to make more, using a bunch of different chemical reactions.

然后身体利用很多不同化学反应开始制造更多腺嘌呤核苷三磷酸。

That “form” is called ATP, if you're familiar with that.

如果你熟形式话，它名字叫做 ATP（腺嘌呤核苷三磷酸）。

Purine-rich foods include shellfish, anchovies, red meat or organ meat.

富含嘌呤食物包括贝类、凤尾鱼、牛羊肉等红肉或内脏。

So the caffeine doesn't even need to compete with the adenosine to fit into those receptors.

所以咖啡不用和腺嘌呤核苷竞争受体。

Now, from a chemical perspective, caffeine can be described as both a methylxanthine and an alkaloid.

从化学角度来看，咖啡既可以被描述为甲基黄嘌呤，也可以被描述为生物碱。

Adenine will always bind with thymine and cytosine with guanine.

腺嘌呤总是与胸腺嘧啶结合，胞嘧啶与鸟嘌呤结合。

When you exercise, your body uses up its main source of energy, ATP, within a few seconds.

当你锻炼时候，你身体在几秒钟内便耗尽了其能要来源，即腺嘌呤核苷三磷酸。

There are four bases: adenosine, thymine, cytosin, and guanine.

腺苷、胸腺嘧啶、胞嘧啶和鸟嘌呤。

The Nitrogenous bases are of four different types: Adenine, Guanine, Cytosine and Thymine.

含氮碱基有四不同类型：腺嘌呤、鸟嘌呤、胞嘧啶和胸腺嘧啶。

There are also medications that help to decrease uric acid levels, which include xanthine oxidase inhibitors like allopurinol.

也有一些药物可以帮助降低尿酸含，包括黄嘌呤氧化酶抑制剂，如别嘌醇。

In more severe cases though, drugs that suppress the immune system, like corticosteroids, azathioprine, or cyclosporine might be prescribed.

在某些更严重病例中，可能会用到免疫抑制药物，如糖皮质激素、硫唑嘌呤和环孢素。

But for the remaining .1%, one person might have an adenine where another person has a guanine.

但对于剩下0.1%，一个人可能有腺嘌呤而另一个人有鸟嘌呤。

Finally, there are some rare stones made of xanthine, which, just like uric acid, is a byproduct of purine breakdown.

最后，还有由黄嘌呤形成罕见结石，同尿酸一样，是嘌呤分解副产物。

Some fish eyes use guanine—one of the chemical building blocks in DNA—and have white eyeshine.

一些鱼眼睛使用鸟嘌呤——DNA 中一化学成分——并且有白色眼睛。

Guanine always pairs with cytosine and adenine always pairs with thymine.

鸟嘌呤总是与胞嘧啶配对，腺嘌呤总是与胸腺嘧啶配对。

So we've stored the energy of that light in ATP and NADPH.

此，我们将那束光中能储存在了三磷酸腺苷（ATP）和烟酰胺腺嘌呤二核苷酸磷酸（NADPH）中。

But it is a stimulant called trimethylxanthine.

但它是一叫做三甲基黄嘌呤刺激物。

NAD, short for nicotinamide adenine dinucleotide, is a coenzyme that occurs naturally in human cells.

NAD， 即烟酰胺腺嘌呤二核苷酸缩写，是一天然存在于人体细胞中辅酶。

So you can be using veteran blue, increasing your NAD.

所以你可以使用美蓝，增加你烟酰胺腺嘌呤二核苷酸。

The series of reactions that generate more ATP in muscles do produce extra protons, which lowers the pH in your muscles.

肌肉中形成更多腺嘌呤核苷三磷酸系列反应确实产生了额外质子，会降低肌肉中酸碱值。
