Well, in this particular case, we have a well defined structure. And because of this well defined structure, the adjacent hydrocarbon chains of these adjacent phospholipid molecules can actually interact very well and form many of these London dispersion forests. But in this particular case, because of the CIS double bond, we have a kink, we essentially have this bend in the chain. And because of that bend, the interactions are not as strong and not as extensive as in this particular case. So we simply have less of these interactions taking place. And because of that, if we have less interactions taking place, what that basically means is the fluidity in this particular case will increase and the melting temperature will decrease.
