Many organic molecules have an end that will dissolve in fat (this would be the hydrophobic end) and an end that will dissolve in water (this will be the hydrophilic end). As the ends are joined together by the rest of the molecule, the molecule has both properties at once and such molecules are frequently used in the formation of organic membranes.
The head of a surfactant molecule is typically hydrophilic, meaning it is attracted to water. This hydrophilic head allows surfactants to dissolve in water and interact with other molecules.
Phospholipids are the organic molecules in cell membranes that permit the diffusion of lipid-soluble materials. They have a hydrophobic tail that repels water and a hydrophilic head that interacts with water, creating a bilayer structure that allows for the passage of lipid-soluble molecules.
Non-polar tail refers to the hydrophobic region of a phospholipid molecule, which repels water molecules. Polar head refers to the hydrophilic region of a phospholipid molecule, which is attracted to water molecules. Together, they form the phospholipid bilayer of cell membranes.
The most notable characteristic is amphipathicity, meaning it is hydrophilic on one end and hydrophobic on the other. This allows it to form a bilayer, of which cell membranes are made. If a molecule were to cross through the membrane, it would need to diffuse through a hydrophilic region, a hydrophobic region, and another hydrophilic region, which is difficult for most molecules. This is why the phospholipid bilayer is a good way to separate a cell from its environment.

Yes, hydrophilic is a property that determines whether a molecule is polar or nonpolar. Hydrophilic molecules are polar, while hydrophobic molecules are nonpolar.
Hydrophilic, or 'water loving' refers to molecules that are easily miscible in water. Polar molecules and ionic compounds are generally hydrophilic, and non-polar molecules are generally hydrophobic.See the Related Questions to the left for more information about how to determine if a molecule is non-polar, polar, or ionic.
If a molecule is hydrophilic, it attracts water molecules. Hydrophilic compounds are soluble in water and can form hydrogen bonds with water molecules.

Amphipathic molecules are molecules that contain a hydrophilic region (water-loving region) and a hydrophobic region (water-hating region). Therefore, phospholipids, which are amphipathic molecules that make up our cell membranes, form into bilayer bio-membranes naturally due to the hydrophobic forces of attraction between each phospholipid molecule and the water-hating nature of it forces the molecules to orientate themselves with their hydrophobic sections facing inward and their hydrophilic sections outward. I hope this helps! :)
hydrophilic
Phospholipids are the most common type of molecule present in bacterial cell membranes. They have a hydrophobic tail and a hydrophilic head, which allows them to form a lipid bilayer that makes up the cell membrane.
No, not all molecules can diffuse through all cell membranes. The ability of a molecule to diffuse through a cell membrane depends on its size, charge, and solubility in lipids. Small, non-polar molecules can generally pass through the lipid bilayer of cell membranes via simple diffusion, while larger, polar molecules may require specific transport mechanisms.
