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 i…nteracts with water, and the hydrophobic tails stays away from water, but mixes with fat. This makes the phospholipids form the phospholipid bilayer.

So do hydrophilic molecules. Therefore, the hydrophobic tails of a phospholipid would want to stay with the oil layer of the salad dressing, while the hydrophilic head of the phospholipid would be attracted to the water layer. It would look like the phospholipid was doing a hand stand in the salad dressing.

Phospholipid bilayers form when two sheets of phospholipid molecules align. The hydrophilic heads in each layer face a surrounding solution, while the hydrophobic tails face one another inside the bilayer. Phospholipid bilayers form spontaneously, with no outside input of energy required.

A phospholipid is named for its two main parts, a phosphate group and a lipid. It's usually drawn with the phosphate group as a circle, and this is referred to as the hydrophilic head. Due to its negative charge, this phosphate group is also polar. The phosphate group and the lipid are connected by a glycerol group.

In a bilayer, the hydrophilic heads of the phospholipids will want to be touching water at all times. So the first layer will form a ring with the heads facing water. This leaves the hydrophobic tails touching the inside of the circle. However, the intracellular environment of a cell is aqueous, or water-based.

The lipids provide the structural integrity for the cell. The lipids found in the membrane consist of two parts: hydrophilic (water soluble) and hydrophobic (water insoluble). The hydrophobic portion of the lipids is the non-polar long hydrocarbon chains of two fatty acids. The fatty acids are present as esters bonded to glycerol.

Every cell is enclosed by a membrane which gives structure to the cell and allows for the passage of nutrients and wastes into and out of the cell. The purpose of the bilayer membrane is to separate the cell contents from the outside enevrionment.

However, the interaction of the hydrophobic inside of the layer acts as a barrier for ionic and polar molecules from entering the inside of the cell. In animal cells cholestrol is inserted between the non-polar chains, and makes up abot 20% of the molecules of the membrane.

The cell membrane is called the phospholipid bilayer because the phospholipids form two distinct lay…ers. In each layer, the phospholipid molecules lie with the hydrophilic heads at the membrane surface and the hydrophobic tails on the inside, in association with cholesterol and small quantities of other lipids.

Hydrophilic = water-loving. Cell membranes are made up of phospholipid bilayers. The head has to be hydrophilic to allow for osmosis and diffiusion. It is polar, water-soluble, and made of phosphorylated alcohol. The tails, which are hydrophobic (water-fearing) and non-polar, are turned inwards. They're made of fatty acids which are not strongly attracted to each other, so the membrane stays flexible. The phospholipid bilayer kinda looks like this:

which part of a phospholipid is hydrophobic
A phosphate group and a lipid part of a phospholipid are hydrophobic.
