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酸性氨基酸，比如谷氨酸与天冬氨酸，它们具有一些以COO-或COOH形式存在的羧基。

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，几乎没有氢离子在周围漂浮，所以那些羧基倾向于呈COO-的形式。
