All of the molecules are called hormones, so a hormone is another name for a ligand that operates in this endocrine fashion.

这些分子都叫做激素,那么激素就是在内分泌系统中,起作用的配体的另一种叫法

Example, protein hormones are insulin which we've talked about before and glucagon, and growth hormone which we haven't talked about but that's very important during periods of life like adolescence, when rapid growth of your bones is occurring.

例如,我们以前讲过的胰岛素,还有胰高血糖素都是蛋白质激素,生长激素也是,尽管我们还没有讲过它,但它在人的青春期阶段,起着非常重要的作用,骨骼在此时期快速生长
