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。

Alanine aminotransferase, or ALT, is mostly found only in the liver, and aspartate aminotransferase, or AST, is found in both the liver as well as other tissues.

比如丙氨酸氨基转移酶（ALT），在肝内最多见；又如天冬氨酸氨基转移酶（AST），可见于肝及其他组织中。

In addition, there were alterations in hepatic function measures: levels of alkaline phosphatase (68 U per liter), alanine aminotransferase (105 U per liter), aspartate aminotransferase (77 U per liter), and lactate dehydrogenase (465 U per liter) were all elevated on day 5 of hospitalization.

此外，肝功能指标也发生了变化：碱性磷酸酶（每升 68 U）、谷丙转氨酶（每升 105 U）、天冬氨酸转氨酶（每升 77 U）和乳酸脱氢酶（每升 465 U）的水平住院第 5 天均升高。
