Nonpolar molecule is one which electrons are shared equally in bonds. Such a molecule does not have oppositely charged ends. This is true of molecules made from two identical atoms or molecules that are symmetric, such as CCl4.

What type of organic molecule requires the action of emulsifiers to be sucessfully digested?
Fat molecules. Water molecule is polar, and therefore water is a good solvent for other polar molecules, dissolving them when they come in contact with one another. Water is not a good solvent for nonpolar molecules, such as fats. A fat has no polar grups to interact with water molecules. An emulsifier, however, can cause a fat to disperse in water. An emulsifier contains molecules with both polar and nonpolar ends. When the nonpolar ends interact with the fat and the polar ends interact with the water molecule, the fat disperses in water, and an emulsion results.
The cell membrane is made up of phospholipids which are molecules?
The cell membrane is made of a phospholipid bilayer with the hydrophilic ends out and the hydrophobic ends in. There are globular proteins in between the bilayer that assist in transport.
Why is water a good solvent?
The arrangement of atoms in a molecule of water causes the molecule to be imbalanced. This imbalance causes a very small magnetic field, so it attracts many types of other molecules and sticks to them. So for example, when dissolving salt into water, the charged molecules of water attract the salt molecules and they stick together easily.A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen. In a covalent bond electrons are shared between atoms. In water, the sharing is not equal. The oxygen atom attracts the electrons more strongly than the hydrogen. This gives water an asymmetrical distribution of charge. Molecules that have ends with partial negative and positive charges are known as polar molecules. It is this polar property that allows water to separate polar solute molecules and explains why water can dissolve so many substances.The solvent properties of water are vital in Biology, because many biochemical reactions take place only within aqueous solutions. When an ionic or polar compound enters water, it is surrounded by water molecules. The relatively small size of water molecules typically allows many water molecules to surround one molecule of solute. The partially negative dipoles of the water are attracted to positively charged components of the solute, and vice versa for the positive dipoles.Since water is polar, it is a good solvent
What can you conclude about the advantage of the cell membrane having hydrophobic ends in the phospholipid bilayer?
Well it prevents polar molecules from passing through freely, giving the membrane its semi-permeable properties.
Is DNA a polar or nonpolar molecule?
DNA is a polar molecule because it has a negatively (-) charged phosphate group attached to the 5' end of the molecule and a negatively charge hydroxl group (OH) attached to the 3' prime end of the molecule.Thus, it is a POLAR molecule which allows it to interact in an aqueous environment.
What are molecules that do not have opposite charged ends?
Molecules that do not have oppositely charged ends are nonpolar molecules.
Molecules that do not have oppositely charged ends are what molecules?
Molecules that do not have oppositely charged ends are nonpolar molecules.
Is a non polar molecules?
A nonpolar molecule is a molecule that shares electrons equally and does not have oppositely charged ends.
What is a non polar?
A nonpolar molecule is a molecule that shares electrons equally and does not have oppositely charged ends.
What molecule that has oppositely charged ends is called?
Those molecules are polar.
What is a non - polar molecule?
A nonpolar molecule is a molecule that shares electrons equally and does not have oppositely charged ends.
None polar molecules?
Non-polar molecules are ususally carbon saturated. Often contain no or very few Nitrogen or oxygens.
Do polar molecules share electrons equally?
Nonpolar molecules are molecules that shares electrons equally and does not have oppositely charged ends. Polar molecules are molecules with a slightly positive end and a slightly negative end as a result of electrons being shared unequally.
A molecule with opposite charges on opposite ends?
It is called polar
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 non polar molecules have both negative or positive ends?
Some but not most non polar molecules have both negative and positive "ends" to their individual bonds. Examples include tetrafluoromethane. By definition, however, a non-polar molecule does not have negative and positive ends to an entire molecule.
