The tail of the phospholipid is non polar. The tail is a long hydrocarbon chain.

Soap is actually both. It is similar to a phospholipid in that it has a polar head and a nonpolar tail.


Which is the effect of having the polar and nonpolar ends of phospholipid molecules oriented as they are in this illustration?



No, that could be a phospholipid that you're thinking of. Water is a polar molecule.


Soap is similar to a phospholipid (of a eukaryatic cell) with a polar head and two nonpolar tails


The phospholipid heads are hydrophillic and prefer the water while the tails are hydrophobic and are shielded from the water.



Lipids, man!Could be the phospholipid bilayer of a cell membrane to be more specific.phospholipidSoap and detergent molecules have a polar head and nonpolar tail to help dissolve an dwash off dirt and oil.


The phospholipid bilayer in cell membranes is both polar and nonpolar. The heads, which face the outside and inside of the cell, are polar. Thus they form hydrogen bonds with the water outside of the cell and the cytoplasm inside the cell. They are called "hydrophilic," which means they love water. The tails are on the inside of the bilayer and are nonpolar. They are hydrophobic, which literally means they are scared of water.




The general term for this property is called "amphipathicity." An example of an amphipathic molecule is a phospholipid.


A polar solute will dissolve in a polar solvent but not a nonpolar solvent. A nonpolar solvent will dissolve in a nonpolar solvent but not a polar solvent.


Nonpolar. No element on its own can be polar.


It's not polar or nonpolar, but ionic.


Honey is Polar and nonpolar


The head (or top) of a phospholipid is polar and the carbon chain tail is non-polar.


The structure of cell membrane allows nonpolar molecules to diffuse, but not polar molecules. Membrane architecture is in the form of a phospholipid bilayer. A single phospholipid has a "head" composed of a polar NH3 group, and two "tails" composed of nonpolar fatty acids. The lipids spontaneously arrange themselves into bilayers with the hydrophilic heads directed outward, and the hydrophobic tails facing inward. Because nonpolar solvents can only dissolve nonpolar solutes, polar molecules cannot mix with the nonpolar inside of the lipid bilayer. A polar molecule cannot cross the cell's lipid membrane without aid from a carrier protein. While this is true, there are multiple forces that dictate whether or not a molecule can cross a phospholipid membrane, including electrochemical gradients and size. Very small and non-polar molecules have a very easy time crossing the phospholipid bilayer. However, very small, polar molecules like water can also cross the phospholipid bilayer due to hydrostatic pressure and concentration gradient differences. Water will, but with some difficulty because of it's polarity. Aquaporins, protein channels embedded into cellular membranes allow for sufficient amounts of water to diffuse into cells.


The phosphate group or "head" of the phospholipid is polar.


There are many things that determine whether something is polar or nonpolar, such as the chemical structure of the molecule. In the case of water, it is polar.


It's polar. If you look at its structure, it has a large number of -OH bonds, which are polar. (Biological molecules that are nonpolar usually have long stretches of -CH bonds).


No. To get them in or out the cell active transport or Facilitated dyfusion is needed.


Mostly nonpolar. Please understand that polar or nonpolar is a continuous range, not an either or.
