These club cells secrete glycosaminoglycans which protect the bronchiolar epithelium.

棒状细胞能分泌糖胺聚糖，来保护细支气管内膜。

Then, there are long chains of sugars called glycosaminoglycans or GAGs, which act like sponges and can hold huge amounts of water.

还有个就是长长的糖原链，叫做“糖胺聚糖”，它就海绵样，能储存大量水分。

The anchors of this framework are proteins called proteoglycans. And from each one sprouts lots and lots of long, starchy strands called glycosaminoglycans, or GAGs, radiating out from those proteins like brush bristles.

这个构架的支柱是蛋白质蛋白聚糖，并从每个蛋白聚糖中长出许多称为糖胺聚糖或 GAG 的长淀粉链，从这些蛋白质中辐射出来，就刷毛样。

The extracellular component includes both the intravascular space - the space within the blood and lymphatic vessels and the interstitial space - the space between cells where you typically find fibrous proteins and long chains of carbohydrates which are called glycosaminoglycans.

细胞外的部分包括管道内空间，即血管和淋巴管内的空间以及间质空间，即细胞之间的空间，通常能找到纤维蛋白和叫糖胺聚糖（即黏多糖）的长链碳水化合物。
