Usually though, bile salts bind up the calcium ions and keep them from binding with and precipitating unconjugated bilirubin.

通常情况下，盐会结合钙离子，以此阻止钙离子与非结合结合并沉淀。

The final portion is called the terminal ileum, and it absorbs vitamin B12 and bile salts which are recycled.

后一部分为末端，以吸收维生B12和汁盐（进行盐循环）。

Bile salts and acids are mostly a product of cholesterol metabolism, so an acid might look something like this and its salt is the anionic form, something like this (ROO-) group.

盐和汁酸是固醇代谢的主要产物，所以汁酸的分子式如图，而盐是阴离子形式，类似于这个（Roo-）基团。
