The question of why these two common liquids refuse to combine is rooted in the intricate dance of molecular forces. Furthermore, mixing increases the disorder, or entropy, of a system.
How Lipoproteins Solve the Oil and Water Mixing Problem in the Bloodstream
The system would then need to find a way to form new interactions, but the interaction between oil and water is weak. In the human body, lipids are transported in the bloodstream thanks to lipoproteins, which act as emulsifiers to temporarily bind fats and water-based blood.
The natural tendency toward higher entropy and lower energy thus favors the oil and water remaining in two distinct phases. Non-polar molecules (like oil) have an even distribution of electrical charge.
How Lipoproteins Enable Oil Transport in the Bloodstream
Non-polar substances, including oils, fats, and waxes, lack these charges and therefore cannot form the necessary interactions with water to break apart and integrate. To understand this separation, one must look beyond the visible surface and examine the hidden interactions of polarity, charge, and energy that dictate how substances behave.
