Through three stories about carbon-carbon double bonds, the series of dialogues between the protagonist Xiaoxi and her family members discuss the three structures and real life applications of alkenes containing the planar carbon-carbon double bond, namely the most basic ethene as a plant hormone, the health effect of cis or trans-unsaturated fatty acids, and the light sensing via the fast conversion of 11-cis-retinal cis-trans in rhodopsin.

Key words: Ethene, trans Fat, 11-cis-Retinal, cis-trans Isomerism
