And these sugar molecules — we call them glycans — interact with molecules from the immune system and microbes directly.

这些糖分子——我们称之为“多糖”——与免疫系统和微生物的分子直接相互作用。

As she hoped, these modified sugars were incorporated into glycans.

正如她所希望的那样，这些修饰的糖被并入聚糖中。

She was then able to attach fluorescent marker molecules to those glycans once they were exposed to the outside world, by fitting the markers with strained-alkyne rings.

然后，一旦这些聚糖暴露在境中，她就可以将荧光标记分子附加到这些聚糖上，方法是将标记物与应变炔相匹配。
