Lipids are really complex molecules on their own right, but because of their particular kind of complexity they allow certain biological structures to form.

脂类本身是非常复杂的分子,但正是它们独特的复杂性,使它们能够形成某些生物结构

I do want to talk about one important subject which you might not have thought too much about and that's lipids, because lipids are so important to the structure of the body because they make up the membranes that form the cells that are the fundamental units.

我的确想要讨论一个重要的主题,这个主题也许你们都没有深入思考过,那就是关于脂类的问题,脂类对身体结构形成十分重要,它是组成细胞膜的基本单位,而细胞膜能够维持细胞形态

They're lipids but they also have a charged portion, a positively charged portion which interacts with DNA.

它虽然是脂类,但一部分带有电荷,其带有的正电荷将与DNA产生静电作用

So you form DNA lipid complexes and because the DNA is complexed with lipids it's more soluble in membranes and more likely to enter cells.

形成DNA脂类复合体之后,因DNA同脂类复合,其脂溶性大大增加,更容易进入细胞
