Plasma membrane contain mainly these molecules that termed amphipathic because
the nature of the molecule has hydrophilic and hydrophobic regions. What are these
molecules and what about the molcule gives it the hydrophilic nature?
Triglycerides provide fatty acid chains that do not interact with water
Triglycerides provide fatty acid chains that do interact with water
Phospholipids contain a phosphate group with highly electronegative oxygens
which allows for hydrogen bonding
Phospholipids contain a phosphate group with highly electropositive oxygens
which allows for hydrogen bonding

Final answer:

Phospholipids have hydrophobic tails and hydrophilic heads that form a bilayer in cell membranes, separating internal and external environments.


Explanation:

Phospholipids are amphipathic molecules that have a hydrophobic (water-fearing) part consisting of fatty acid chains and a hydrophilic (water-loving) part composed of a phosphate-containing group. The hydrophilic head interacts with water, while the hydrophobic tail avoids it. In a membrane, phospholipids align to form a bilayer with hydrophobic tails inside and hydrophilic heads facing the watery environment, creating a barrier between the cell's interior and exterior.
