由于在无生命的地球上，天然有机化学系统很可能形成较简单的膜，所以本次古生物工程也采用较简单的脂质——主要是普通脂肪酸。

Because simpler membranes are more likely to have formed from the natural organic chemistry factory on prelife Earth, the protocell project is working on plainer lipids - chiefly ordinary fatty acids.

显然，有必要把分子繁殖，代谢，脂质边界膜和原生细胞的繁殖都放在一起综合考虑。

Obviously, it is necessary to bring molecular reproduction, metabolism and something like a lipid bounding membrane and reproduction of a protocell together.

another thing that you'd find if you looked inside the axon terminals of any of these pre-synaptic membranes, you'd find lots of vesicles or some membrane bound compartments that contain special chemicals called neurotransmitters.

如果你仔细观察,突触前膜的轴突末梢内部,你会发现很多小泡,即膜包被的结构,包含有称为神经递质的特殊化合物
