Cell membranes are constructed from phospholipids, molecules with a polar head and non-polar tails. London Dispersion Forces Water molecules engage in extensive hydrogen bonding, a specific and relatively strong type of intermolecular attraction.
Understanding Predictable Oil Water Behavior and Emulsion Formation
Practical Manifestations and Emulsions The practical consequence of this molecular incompatibility is the immediate separation seen in a glass of water with olive oil. Nature favors processes that increase entropy, or disorder.
However, this separation can be temporarily overcome with vigorous shaking or stirring, creating an emulsion. When attempting to mix, the water molecules would have to disrupt their strong hydrogen bonds to accommodate oil molecules, which they cannot do energetically.
Understanding Predictable Oil and Water Behavior in Mixtures
An emulsifier, such as lecithin in egg yolks, has a polar end that bonds with water and a non-polar end that bonds with oil, stabilizing the droplets and preventing them from coalescing. In stark contrast, oil is typically non-polar, consisting of long hydrocarbon chains where electrons are shared more evenly.
