Saturation = extent of packing

Fully saturated fatty acids in the extended form pack into nearly crystalline arrays, stabilized by many hydrophobic interactions.

#Unit 1. Structure and Function of Biomolecules

The presence of one or more fatty acids with cis double bonds interferes with this tight packing and results in less stable aggregates.
