They did it by removing groups of atoms called hydrogen-bond donors from the original molecules and adding a ring of carbon and hydrogen atoms.
他们移除氨噻唑分子上一组提供氢键的原子，并加上一个碳氢环。修饰后的氨噻唑分子看起来更像胆固醇分子。
In DNA a C can only hydrogen-bond with a G, and an A only with a T, these interactions, formed by so called hydrogen bonds, hold the two strands together.
在DNA中C只能和G通过氢键连接，A只能和T连接，通过所谓氢键发生的这些作用将两条链连在一起。
From the structure of hydrogen-bond in the compound, this paper discusses the influence of hydrogen-bond on the physical and chemical properties of the compound.
本文从化合物中氢键的结构出发，探讨了氢键形成对化合物的物理性质和化学性质的影响。

As we see a little bit later, I could talk about the carbon-hydrogen bond in methane where there is a plurality of bonds. In this case, there is only the one bond but I just want to get the formulas.
因为我们后来看到一点点，我能讨论甲烷中的碳氢共价键,那有许多共价键，这种情况下，这只有一条共价键,但我想得到氟。
