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

这些糖——我们称之为“多糖”——与免疫系统和微生物的接相互作用。

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

正如所望的那样，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外界环境中，就可以将荧光标记附加到这些聚糖上，方法是将标记物与应变炔环相匹配。
