Abstract

Polyphenol oxidase oxidizes several proteins that contain tyrosine. During aging, when synthesis and replacement of catabolized proteins are lagging, the relative proportion of oxidized species might reach high values, thus impairing physiological function. A mathematical analysis verifies this assumption.

摘要

多酚氧化酶会氧化几种含有酪氨酸的蛋白质。在衰老过程中，当分解代谢的蛋白质的合成和替换滞后时，氧化产物的相对比例可能会达到很高的值，从而损害生理功能。数学分析证实了这一假设。
