摘要

应对人血白蛋白制备与储存过程中复杂的温度、光照等条件,提高白蛋白的稳定性十分必要.本文从配体与白蛋白结合的角度,阐述了配体对白蛋白的稳定效果和简单的稳定机制.通过综述对比可以得出,常见配体辛酸钠主要起到提升热稳定性作用,常见配体N-乙酰-L-色氨酸主要起到提升抗氧化性的作用,而相较于N-乙酰-L.色氨酸,近些年研究的N-乙酰-L-甲硫氨酸具有更好的抗氧化性和抗光氧化性.

Abstract

It is necessary to improve the stability of human serum albumin in response to the complex temperature,light and other conditions during the manufacture and storage.In this paper,the stabilization effect and simple stabiliza-tion mechanism of ligands on albumin were described from the perspective of ligand binding to albumin.Through review and comparison,it can be concluded that the common ligand sodium octanoate mainly plays a role in improving thermal stability,and the common ligand N-acetyl-L-tryptophan mainly plays a role in improving antioxidant activity,N-acetyl-L-methionine has better antioxidant and anti-photooxidation than N-acetyl-L-tryptophan.
