Why are proteins amphipathic?
Because the heads of the phospholipids are hydrophilic (water loving) and the tails of the phospholipids are hydrophobic (water hating). The tails are pointing towards each other and the heads are facing the membranes.
When mixed with water phospholipids spontaneously form membranes. what properties of phospholipids cause this to happen?
Hydrophilic phosphate groups that are attracted to water and hydrophobic fatty acid tails that avoid water.
How do phospholipids associate with water to provide structure to cell membranes?
In a water solution, phospholipids form a bilayer where the hydrophobic tails point towards each other on the interior and only the hydrophilic heads are exposed to the water. Phospholipid bilayers are critical components of cell membranes.
Tails of phospholipids that dont like water?
Phospholipids have a lipid tail. This is non-polar and therefore hydrophobic (water hating). The phosphate head is polar and hydrophilic (water-loving).
Why are the outside heads of phospholipids located on the outside of the cell membrane?
Tails are Hydrophobic
How are phospholipids arranged in biological membranes?
double layer with hydrophobic tails facing inward toward each other
The phospholipid molecules of most membranes have?
A hydrophilic head and two hydrophobic tails.

Do Phospholipids have hydrophilic and hydrophobic regions?
Yes, hydrophilic phosphate heads and hydrophobic modified carbohydrate tails.

Phospholipids have a lipid tail. This is non-polar and therefore hydrophobic (water hating). The phosphate head is polar and hydrophilic (water-loving).
How do the hydrophobic and hydrophilic properties of phospholipids help in maintaining the structure of the cell membrane?
Hydrophilic molecules are attracted to water. Hydrophobic molecules are not attracted to water, but they are attracted to each other. Phospholipid molecules are unusual because they are partly hydrophilic and partly hydrophobic. The phosphate head is hydrophilic and the two hydrocarbon tails are hydrophobic. In water, phospholipids form double layer with the hydrophilic heads in contact with water on both sides and the hydrophilic tails away from water in the centre. This arrangement is found in biological membranes. The attraction between the hydrophobic tails in the centre and between the hydrophilic heads and the surrounding water makes membranes veery stable.
Where are the water in-soluble hydrophobic tails of the phospholipids bilayer located?
Cytoplasm of the cell
Why are the outside heads of phospholipids located on the outside of the cell membrane?
Tails are Hydrophobic
How would a non polar molecule such as a fat or oil travel through the plasma membrane?
The inside of a membrane is "hydrophobic" because of the hydrophobic fatty acid tails of the phospholipids.
