So the bacteria use an enzyme called glucosyltransferase to cut the bond between them, use the fructose for energy, and add the glucose to a growing chain of glucose molecules called a glucan.

菌会通过糖基转移酶分解它们之间化学键，然后利用果糖供能，并糖连接到一种叫作聚糖延伸糖链上。

Glucans allow the bacteria to attach firmly to the surface of the tooth, and form dental plaque, which is a sticky collection of bacteria, proteins from saliva, and dead cells from the lining of the mouth.

聚糖使得菌可以牢固结合在牙齿表面，形成牙菌斑；牙菌斑是一种由菌、蛋白质、唾液和口腔内凋菌一起组成一种黏糊糊混合物。

And unlike wheat and most other grains, oats contain large amounts of a specific type of fiber called beta glucan, which studies have consistently linked to healthier cholesterol scores and a reduced risk for diabetes and cardiovascular disease.

与小麦和大多数其他谷物不同，燕麦含有大量称为 β 聚糖特定类型纤维，研究一直将其与更健康胆固醇评分以及降低患糖尿病和心血管疾病风险联系起来。
