组成细胞的最基本元素是C元素。碳原子间可以通过碳碳单键相结合,也可以通过双键或三键相结合,形成不同长度的链状、分支链状或环状结构,这些结构称为有机物的碳骨架。
但是建立一个碳骨架并不容易。
磷脂包含一个通过磷酸基附着在甘油的三碳骨架上的头部,这里是一个胆碱。
Phospholipids contain a head group, choline in this case, that is attached the phosphate group to a three carbon glycerol backbone.
红外光谱表明了该双改性树脂的碳骨架上引入了桐油分子长碳链,具有一定的柔韧性和油溶性。
IR spectra showed that long chains of molecules of tung oil were bonded on the skeleton of boron phenolic resin.
So our skeleton tells us that carbon is in the middle, so we'll put the h on one side, and the n on the other side there.
我们的骨架告诉我们碳原子应该放在中间,因此我们把氢原子放在一边,把氮原子放在另外一边。
