The kinked configuration is called the" cis isomer" and the straight one is the trans isomer.

结状排列成为“顺式异构体”线状排列，成为“反式异构体”。

Well we know that they're unsaturated alkenes because saturated fats don't have double bonds, and thus, can't have cis- and trans- isomers.

我们知道它们是不饱和烯烃， 因为饱和脂肪没有双键，因此不会有顺式和反式异构体。
