What do you mean by "single hydrogen bonds"? C-H bonds are always single bonds, and I am unfamiliar with any kind of "double" hydrogen (intermolecular) bonding. Unsaturated fats, by definition, have at least one double bond, between carbon atoms.

Sorry, you are correct. I fixed my comment. What I meant was the carbon-carbon double bonds replace a hydrogen atom that would otherwise be there, so the bond can be easily broken when interacting with other molecules (because the carbon-carbon bond is electron rich).
