This happens because albumin has acidic amino acids, like glutamate and aspartate, which have some carboxyl groups that are in the form of COO- or COOH.

这是因为白蛋白含有性基，比如谷与天冬，们具有一些以COO-或COOH形式存的羧基。

When there's a high pH, or alkalosis, there are very few protons floating around, and so those carboxyl groups tend to be in the COO- form.

当血液pH值高或碱中毒时，几乎没有氢周围漂浮，所以那些羧基倾向于呈COO-的形式。

Those are acids that have this carboxyl group in it.

这些是含有羧基的。

This would be our carboxyl group, our amino group, so everyone of these amino acids has that same part to it.

这将是我们的羧基，我们的基，所以每个基都有这一部分。

We have a carboxyl group, a functional group, on this side which is a carbon, two oxygens and hydrogen.

我们这边有一个羧基， 即功能团，由一个碳、两个氧和一个氢组成。
