The compound with both a non-polar tail and a polar head is called an amphiphilic molecule. An amphiphilic molecule can form micelles. These such micelles is how detergents dissolve dirt. A big example of micelles are phospholipids.

All nucleic acids contain a functional group that is also found in the subset of lipids that make up biological membranes?
phosphate group; Although most lipids are completely nonpolar, phospholipids are amphipathic (i.e., polar on one end and nonpolar on the other) due to the presence of a phosphate group. This amphipathic structure makes phospholipids ideal to form the protective membrane barriers found in living cells. Phosphate groups are also found in all nucleotides, the monomers of nucleic acids.
Which lipids are polar?
There are 4 classes of lipids. Neutral fats, phospholipids, steroids, and eicosanoids. Phospholipids are polar.
Is water a polar or nonpolar molecule?
A polar molecule
Which part of the cell membrane non-polar and prevents the cell from dissolving?
Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
Can polar molecules and molecules that have chargers sneak through the nonpolar middle portion of the phospholipid bilayer?
No, they are not. Micelles are formed by amphipathic molecules, that is molecules having both poplar and nonpolar regions, such as phospholipids or fatty acids. The polar region stays to the outside of the sphere as it can interact with water or some other polar solvent and the nonpolar regions are forced to the center.
Does the phospholipids contain a non polar component and a charged polar component?
Yes, they do. Phospholipids contain a hydrophilic (polar) head and a hydrophobic (nonpolar) tail. The hydrophilic (polar) head contains the phosphate groups, which account for the reason why the head is polar since each phoshpate has a net charge of -2. The tail consists of long chains of hydrocarbons, which are nonpolar/hydrophobic due to the symmetry of the chains.
Do phospholipids contain hydrogen?
Yes, they do. Phospholipids contain a hydrophilic (polar) head and a hydrophobic (nonpolar) tail. The hydrophilic (polar) head contains the phosphate groups, which account for the reason why the head is polar since each phoshpate has a net charge of -2. The tail consists of long chains of hydrocarbons, which are nonpolar/hydrophobic due to the symmetry of the chains.
What are lipids with polar heads and nonpolar tails called?
phospholipids
Where are the polar and non polar layers in the plasma membrane located?
the two fatty acid tails of the phospholipids are nonpolar, whereas the head is polar
How do Phospholipid interact with water?
Phospholipids do not interact with water, because water is polar and lipids are nonpolar.
Is bacteria and virus polar or non polar?
Bacteria and viruses are not molecules and are neither polar nor nonpolar. The contain both polar and nonpolar molecules.
Why is one end of the phospholipids polar and the other nonpolar?
what is a potential danger of excess cholesterol in the human body
How does the structure of phospholipids linear molecules with a polar end and a nonpolar end relate to their function in the cell membrane?
Which is the effect of having the polar and nonpolar ends of phospholipid molecules oriented as they are in this illustration?
Do phospholipids spontaneously form Liposomes in Nonpolar solvents?
No-- Liposomes are only formed in polar solvents (i.e. water)
Does Mg3N2 contain nonpolar bonds?
it is an ionic compound so the words ..polar and nonpolar are meaning less....
Are lipids polar or nonpolar?
nonpolar or polar
Why do phospholipids form double layers?
Phospholipids are composed of a polar head group and a hydrophobic tail. These phospholipids line up so that the head groups and tail groups are side by side to form a single layer due to the interactions between the head groups and the tail groups. Two of these layers line up with the hydrophobic tail groups facing each other to prevent the hydrophobic groups away from the polar head groups of other phospholipids and from the water in the surrounding environment.
