What part of the plasma membrane is hydrophobic?
proteins
phospholipid “heads”
phospholipid “tails”
sugar groups

The hydrophobic part of the plasma membrane is the phospholipid “tails.” These tails consist of long hydrocarbon chains that repel water, helping to create a barrier that separates the internal environment of the cell from the outside. This unique property is crucial for maintaining cellular integrity and function!

On the other hand, the phospholipid “heads” are hydrophilic, meaning they love water. This creates a bilayer structure with the tails facing inward, shielded from water, while the heads interact with the aqueous environment. It’s a beautifully simple setup that allows cells to control what enters and exits!
