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，有一系列丝氨、氨残基异常基化，导致它们无法连接。

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

其有丝氨氨残基，是o链基化的，这意味着它们的氧上有一个分子，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.

基本氨基，简称 EAA，是我们身体需要但不能自己产生的氨基，其有 9 种：组氨，异亮氨，亮氨，赖氨，蛋氨，苯丙氨，氨，色氨缬氨。
