For example, by random folding, the amino-acid chain of the enzyme ribonuclease, a small protein, could adopt more than 1040 different shapes, which would take billions of years to explore.

例如，通过随机折叠，核糖核酸酶(一种小型蛋白质)的氨基酸链能形成超过1040种不同的结构，单这一种蛋白质就需要数亿年的时间来探索。

And then linked to the glycerol instead of a third fatty acid chain is a water soluble molecule, like a salt.

但连到甘油上的第三个基团不是脂肪酸链,而是一种水溶性的分子,像盐一样
