Lipid bilayers are made up of phospholipids that have variable head groups and fatty acid chains.
This lipid bilayer is known as amphipathic, meaning the hydrophilic head region of the lipid molecule is polar while the hydrophobic tail regions are non-polar.
The electrical conductance of the lipid bilayer is very low, lower even than thin glass. The lipid bilayer acts as a very good electrical insulator and has direct bearing on the way in which the proteins embedded in the lipid bilayer will behave. Researchers have shown the bilayer has conductance orders of magnitude lower than that measured in the cell membrane. Demonstrating that the conductance is not performed across the lipid bilayer, it is the proteins embedded in the bilayer which perform that function.

∙ 9y agoThe phospholipid bilayer is a biological membrane where the fatty acid chains in each of the layers point towards the center of the membrane. The bilayer is the framework in which the other components of the membrane are embedded.

Is there a phospholipid bilayer membrane surrounding the nucleus?
A double phospholipid bilayer surrounds the nucleus.
What are two layers of phospholipid?
two layers of phospholipids form foundation of biological cell membranes.
What is the phospholipid bilayer that surrounds and maintains integrity of a cell called?
The phospholipid bilayer that surrounds and maintains the integrity of the cell is called a plasma membrane.
What part of the cell membrane make up the bilayer?
It's called the phospholipid bilayer. It's made of phospholipids and some other varients of lipids.
Which type of molecule forms the cell membrane?
The basic structure of cell membranes is a phospholipid bilayer. Phospholipids have a phosphate group (the head) and a lipid tail.
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...
The cell membrane is made of what double layer?
Phospholipid bilayer
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 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 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.
What is the double layered sheet that makes up nearly all cell membranes called?
60%phospholipids and 30% proteins and10% carbohydrates
Is there a phospholipid bilayer membrane surrounding the nucleus?
A double phospholipid bilayer surrounds the nucleus.
Cell membrane made up of?
Phospholipid bilayer and embedded proteins and sugars
A plasma membrane is made up of a?
lipid bilayer
What is a key structural component of a cell's membrane?
Cell membranes are made of a lipid bilayer with various proteins interspersed.
Why do integral proteins stay in place in the phospholipid bilayer?
Integral proteins are able to stay in the phospholipid bilayer because of the way they fold. Proteins have both hydrophic and hydrophilic regions that correspond to the regions of the phospholipid bilayer.
