Glycolipids contain hydrophilic heads. These hydrophilic heads interact with each other and form a hydrophilic coating on each side of the bilayer point towards the polar solvent.

What can assemble into layers due to their charged hydrophilic heads?
phospholipids
Do hydrophilic heads on plasma membranes attract or reple water?
Attract
Components of cell membrane?
hydrophilic phospolipids and proteins... you can use 'simple wikipedia' if the technical terms aren't necessary
What are characteristics of phospholipids?
They have a hydrophilic head which contains a phosphate group and hydrophobic heads that are made up of chains of fatty aids.
What major types of lipid are found in the plasma membranes?
Phospholipids, cholesterol, & glycolipids.
Water-loving heads of phospholipids?
hydrophilic
What part of a lipid is hydrophobic?
The tails of lipids are hydrophobic and the heads are hydrophilic hope this helped=) The tails of lipids are hydrophobic and the heads are hydrophilic hope this helped=)
Do Phospholipids have hydrophilic and hydrophobic regions?
Yes, hydrophilic phosphate heads and hydrophobic modified carbohydrate tails.

Are phospholipids both hydrophilic and hydrophobic in nature?
Yes they are. The two fatty acid tails of the molecule are hydrophobic(repel water) but the phosphate head(negatively charged) is hydrophilic (attached to water)thus making it amphipathic. In biological system phospholipids often occur with other molecules(e.g.,proteins,glycolipids,cholesterol) in a bilayer such as cell membrane.Lipid bilayer occur when hydrophobic tails line up against one another,forming a membrane with hydrophilic heads on both sides facing the water
Are the lipids associated with the biological membrane hydrophobic or hydrophilic?
Hydrophyllic heads and hydrophobic tails.
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.
What molecules make up the channels in the membrane?
The lipid molecules (mostly phospholipids) that make up the membrane have a polar, hydrophilic head and two hydrophobic hydrocarbon tails. When the lipids are immersed in an aqueous solution the lipids spontaneously bury the tails together and leave the hydrophilic heads exposed. Thus this is a handy membrane to use, because it can automatically fix itself when torn. There are three different major classes of lipid molecules - phospholipids, cholesterol, and glycolipids. Different membranes have different ratios of the three lipids.
Why is a phospholipid both hydrophilic and hydrophobic?
They have both hydrophilic and hydrophobic heads. In a lipid bilayer, the hydrophilic head of the phospholipid faces the outside of the membrane while the hydrophobic head faces the the hydrophobic head of another phospholipid.
What are characteristics of phospholipids?
They have a hydrophilic head which contains a phosphate group and hydrophobic heads that are made up of chains of fatty aids.
