In IgA nephropathy, though, there is abnormal glycosylation of these serine and threonine residues, causing them to be galactose-deficient.

而在IgA肾病，有一系列丝、残基异常糖基化，导致它无法连接半乳糖。

Among these are serine and threonine residues which are O-linked glycosylated, meaning they have a sugar molecule, specifically galactose, attached to their oxygen.

其有丝和残基，是o链糖基化，这意味着它上有一个糖分子，半乳糖居多。

Essential amino acids, or EAAs, are amino acids that our body needs but cannot produce on its own, and there are 9 of them: Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

基本基，简称 EAA，是我身体需要但不能自己产生基，其有 9 种：组，异亮，亮，赖，蛋，苯丙，，色和缬。
