A lipid bilayer forms spontaneously whenever a collection of phospholipids is placed in water. This is because the amphipathic lipids (lipids having both polar and nonpolar regions) double up and put hydrophilic ends toward the outside and inside of the cell, whereas the hydrophobic tails are held in between the heads.
A phospholipid is comprised of 1 polar head and two non-polar (fatty-acid) tails
o<>o
The polar region is comprised of a phosophate group (water-soluble)
The non-polar region is comprised of fatty acids (water-insoluble)

Within a lipid bilayer which part of the phospholipid is in contact with water?
The polar head group.
Is there a part of the phospholipid bilayer that is non polar?
The tails, the part that doesn't contain phosphorus, are non polar and they are hydrophobic (afraid of water).
What are the specialized parts of a phospholipid bilayer?
The Phospholipid Bilayer is made up of phospholipids. These phospholipids have a hydrophillic head, and a hydrophobic tail. They are structured so that the hydrophillic head interacts with water, and the hydrophobic tails stays away from water, but mixes with fat. This makes the phospholipids form the phospholipid bilayer. The Phospholipid Bilayer has intrinsic proteins and extrinsic proteins attached, which may have glycoproteins attached to them. Glycolipids may also be attached to the hydrophillic heads of the phospholipid. Cholestrol is also part of the phospholipid bilayer, which adds strengh to the structure.

What is the basic structure of the plasma membrane?
The framework of the cell membrane is formed by the lipid bilayer. The lipid bilayer is composed of two layers of fat cells organized in two sheets. This is what provides the barrier that makes the boundaries of the cell.
What is Phosphate heads?
also can be known as polar head since phosphate is polar found in phospholipid bilayer also can be known as polar head since phosphate is polar found in phospholipid bilayer Was this right? i would like to know...
What is a phosphate head?

What are two layers of phospholipid?
two layers of phospholipids form foundation of biological cell membranes.
A molecule with a polar head and two non polar tails?
Lipids, man!Could be the phospholipid bilayer of a cell membrane to be more specific.phospholipidSoap and detergent molecules have a polar head and nonpolar tail to help dissolve an dwash off dirt and oil.
Within a lipid bilayer which part of the phospholipid is in contact with water?
The polar head group.
What is the significance of the phosphate group in a phospholipid?
I believe the phosphate give the phospholipid a polar region which allows it to interact with water (also polar). This is the basis for the formation of the lipid bilayer.
Is there a part of a phospholipid bilayer that is polar?
The tails, the part that doesn't contain phosphorus, are non polar and they are hydrophobic (afraid of water).
When phospholipid molecules are placed in water they form bilayer membranes Describe what you think happens to cause the formation of the bilayer membranes?
The hydrophobic and hydrophilic effect. The nonpolar tails join together in the middle of the bilayer away from water and the polar heads that can tolerate water are on the outside of the bilayer.
What is another name for the phospholipid bilayer?
It depends on which lipid bilayer you're talking about. There is the phospholipid bilayer that surrounds eukaryotic cells, cholesterol phospholipid bilayers, protein lipid bilayers, phase transition lipid bilayer, lipid bilayer membrane...
What is a phospholipid bilayer and where would you find it?
Phospholipids are polymers made up of two fatty acids, glycerol, a phosphate group and a polar molecule. A cell's membrane consists phospholipids where they form two layers (with the polar molecules facing opposite ends) to separate the interior of the cell from the outside environment. This is called a phospholipid bilayer.
Is there a part of the phospholipid bilayer that is non polar?
The tails, the part that doesn't contain phosphorus, are non polar and they are hydrophobic (afraid of water).
What is a double layer of phospholipids?
A cell's membrane (plasma membrane) is made of a phospholipid bilayer where the hydrophillic phosphate groups form the two outer sides of the bilayer and the hydrophobic fatty acid chains are the interior.
