Citric acid doesn't do that, but makes a very clean sour that's more fruity.

柠檬酸不会这样，但会种非常干净酸，更有水果味。

They put ascorbic acid, sodium ascorbate, sodium citrate, citric acid, and potassium sorbate on me.

们给我注射了抗坏血酸、抗坏血酸钠、柠檬酸钠、柠檬酸和山梨酸钾。

The spices are mixed with lovage seeds and citric acid for a hint of sourness.

加入了复活草籽和柠檬酸可以增添点酸味。

When energy is needed - all three monosaccharides are metabolized through glycolysis, then the citric acid cycle, and oxidative phosphorylation.

当机体需要能时，三种单糖就会通过糖酵解、三羧酸循环、氧化磷酸化进行能代谢。

It tastes sour because it has a lot of citric acid.

它尝起来很酸因为它含有大柠檬酸。

I don't know what citric acid is.

我不知道什么是柠檬酸。

There is also vinegar or citric acid.

还有醋或柠檬酸。

But they CAN move into an ionic solution, an ionic solution like a dilution of citric acid, and that is our electrolyte.

但是它们可以在离子溶液里面流动，离子溶液，比如说稀释柠檬酸，就是我们电解液。

I've got some of my own favorites, like for example, pomegranate juice, arugula, the citric, maybe sometimes some oranges.

我自己也有些喜欢，比如石榴汁、芝麻菜、柑橘类水果，有时候还会吃些橙子。

It wouldn't swim towards them, but crucially, it could still swim towards other things roots release, like citric acid.

它不会游向它们，但关键是，它仍然可以游向根系释放物质，比如柠檬酸。

This stuff contains mainly citric acid and an enzyme cocktail that help keeps semen liquified -- and thus easier to move and swim through.

这些分泌物主要含有柠檬酸和种混合酶，有助于保持精液液化，从而更容易移动和游泳。

Next up is citric acid, which is responsible for that bitter taste in oranges, lemons, limes, and lots of other citrus fruits.

接下来是柠檬酸，它负责橙子、柠檬、酸橙以及许多柑橘类水果中苦味。

So when that's mixed with the citric acid, it kind of creates that same sort of tangy flavor profile, which is awesome.

所以当它与柠檬酸混合时，它会同样浓郁味道，这太棒了。

Citric acid is a clean sour, but malic acid makes you salivate, this is why lemon lime drinks are often seen as being more refreshing, because your mouth almost instantly becomes wet.

柠檬酸是种干净酸味，但是苹果酸会让你流口水，这就是为什么柠檬酸橙饮料经常被认为更提神，因为你嘴几乎立刻变湿了。

Blueberries have citric acid in it, so we're adding a dry form of citric acid to this because without it, the blueberry would taste sort of blueberry, but part of the flavor profile would be missing.

蓝莓含有柠檬酸，所以我们在中加入了种干柠檬酸，因为没有它，蓝莓尝起来有点像蓝莓，但是部分味道会丢失。

And so you don't have to remember the names of these, but this is succinate dehydrogenase and it's a cool enzyme that's used both in the citric acid cycle and the electron transport chain.

因此，你不必记住这些名称，但这是琥珀酸脱氢酶， 它是种很酷酶， 既用于柠檬酸循环， 也用于电子传递链。

And so in every step of photosynthesis, in every step of cellular respiration, glycolysis, citric acid cycle, all of those chemical reactions remember have to have an enzyme that's associated with them that can speed up that reaction.

因此，在光合作用每步、细胞呼吸每步、糖酵解、柠檬酸循环中，所有这些化学反应都需要有种与之相关酶，能够加速该反应。

In the 1920s and 1930s, biochemists—led by Hans Krebs and Carl and Gerty Cori—began to work out many of the central metabolic pathways of life: the citric acid cycle, glycogenesis and glycolysis, and the synthesis of steroids and porphyrins.

在二十世纪二三十年代，由汉斯·克雷布斯（Hans Krebs）和卡尔（Carl Krert）和格蒂·科里（Gerty Cori）领导物化学家开始研究许多命中心代谢途径：柠檬酸循环，糖原合成和糖酵解，以及类固醇和卟啉合成。
