From analytical oddity to conformational study. A rare N‐glycan with a galactosylated bisecting GlcNAc present in human serum immunoglobulin (IgG1) was obtained by chemoenzymatic synthesis from A and derivatized with a lanthanide tag (B). Paramagnetic NMR studies revealed a conformational behavior deviating from that of the non‐bisected biantennary N‐glycan.

用β1,4-半乳糖基化的二等分GlcNAc基序进行N-聚糖的高效化学合成。

从分析怪异到构象研究。人血清免疫球蛋白(IgG1)中存在半乳糖化二等分GlcNAc的稀有N-聚糖是通过化学酶法从A中获得的,并用镧系元素标记(B)衍生化。顺磁NMR研究表明其构象行为与未等分的双天线N-聚糖不同。
