The phospholipid bilayer is fluid due to the unsaturated hydrocarbon tails of phospholipids found in the hydrophobic region. These unsaturated hydrocarbon tails do not have all the hydrogen it can possibly have, so carbon forms a double bond. This double bond within the tails causes a kink in the tail, which prevents tight packing within the hydrophobic region. Preventing the tight packing makes the bilayer more fluid, which all membranes need to be fluid for it to be able to work. Being solid will alter the permeability and affect the enzymes.

∙ 11y agoThe usual phospholipid that we encounter is those found in the cell membrane, namely the membrane phospholipid. They are the predominant lipids of cell membrane.
They can act as:
1) reservoir of intracellular protein messengers such as phosphoinositol biphosphate. This is obtained from the cleavage of phosphatidylinositol by Phospholipase C. Phosphoinositol biphosphate is one of the most important secondary messenger in the cell signalling pathway of human.
2) anchors to cell proteins
On the other hand, phospholipids also exist out of cell membrane. These are non-membrane phospholipid. Some examples are:
1) Dipalmitoylphosphatidylcholine (DPPC) is a component of lung surfactant. Secreted by granular pneumocytes, it decreases surface tension of fluid layer, reducing pressure required to reinflate alveoli.
2) Phospholipid is also an essential component of bile, where their detergent properties (amphipathic) aid in the solubilzation of cholesterol. Phosphatidylcholine (lecithin) and bile salts are both the major components of bile.
3) Act as building blocks of the biological cell membranes in virtually all organisms
4)Participate in the transduction of biological signals across the membrane.
5)Act as efficient store of energy as with triglycerides.
6)Play an important role in the transport of fat between gut and liver in mammalian digestion.
7)An important source of acetylcholine which is the most commonly occuring neurotransmitter substance occuring in mammals.

The double layer of phospholipids is called a what?
The double layer of phospholipids is called the phospholipid bilayer. It forms the basis of every membrane, both the plasma membrane and all internal membranes.The idea that the bilayer has protein molecules embedded in it is the essence of the fluid mosaic model of the cell membrane.
What is the primary molecule of the cell membrane?
membrane lipid which is made up of phospholipids and glycolipids. both phospholipids and glycolipids makes up glycerolipid.
Which molecule are used to form cell membrane?
The main component of cell membranes is phospholipids - which form a bilayer (with polar heads facing outwards and tails facing inwards).
What makes up the membrane of a cell?
The membrane of a cell is basically made up of a mixture of lipids and proteins. The other components of a membrane of a cell are phospholipids and glycoproteins.
Hydrophobic interactions of the tails of phospholipids can produce a. a cytoskeleton. b. a protein membrane. c. a nonpolar membrane. d. a lipid bilayer. e. hydrolysis of the fatty acid?
a lipid bilayer
. The inside of a membrane bilayer is .?
The cell membrane's bilayer structure is made up of phospholipids.
What is the plasma membrane compose of?
Bilayer of phospholipids
Does the cell membrane consist of two lipid layers?
The plasma membrane is made of a bilayer lipid membrane (phospholipids) with proteins that are present in a mosaic pattern. The membrane is semi fluid.
Are phospholipids found in the cell membranes of animal cells?
yes, they are orgranized in the bilayer of the plasma membrane.
What molecule forms the lipid bilayer of the cell membrane?
phospholipids
What are the different lipids that are in cell membrane?
Phospholipids are found in the cell membrane which form the bilayer
What can a cell membrane be described as a double layer of?
The basic structure of a cell membrane is the phospholipid bilayer. Both layers of phospholipids have their hydrophobic tails facing towards the centre of the bilayer, whereas the hydrophilic heads neighbour the cell surroundings and the cytoplasm itself.
Where do phospholipids get used structurally?
Phospholipid bilayer the forms the plasma membrane.
What kind of lipids make up the bilayer that form the membrane?
Phospholipids
The double layer of phospholipids is called a what?
The double layer of phospholipids is called the phospholipid bilayer. It forms the basis of every membrane, both the plasma membrane and all internal membranes.The idea that the bilayer has protein molecules embedded in it is the essence of the fluid mosaic model of the cell membrane.
What is the material that composes the cell membrane?
The cell membrane is composed of phospholipids. They form a bilayer for the cell.
What is an example of a lipid bilayer?
An example of a lipid bilayer is the cell membrane. It is formed by two layers of phospholipids, which have a polar head and non polar tails, providing an anfoteric environment in which phospholipids arrange to form a membrane.
