Cholesterol has a small, water-soluble polar region that dissolves in water, but nearly the entire cholesterol molecule is non-polar, which will NOT dissolve in water - like oil. This makes cholesterol an example of an amphipathic molecule - part water-soluble, part water-insoluble.
Lipids in general are considered Amphipathic. Meaning they have a region that is hydrophilic as well as a region that is hydrophobic. For example, the carboxyl group (COOH) on the end of a fatty acid is considered hydrophilic because it can interact with water while the long hydrocarbon tail of the fatty acid is hydrophobic having no ability to interact with water. This amphipathic nature of lipids is essential in the formation and function of cell membranes (lipid bilayers)
Yes there are hydrogen bonds between cholesterol and phospholipid molecules. These bonds are better known as hydrogen-bonded water bridges.
Yes! it is the most hydrophobic molecule, causing it be really insoluable in water
Phosphatidylcholine is really considered amphipathic because it contains a hydrophobic region and a hydrophilic region.
Yes, cholesterol is an organic molecule. It is an important component of plasma membranes and is a precursor to other important organic molecules.
because of water molecles
Yes it is hydrophilic. It is a lipid
It is a lipid. It is hydrophobic molecule
no
Oil is one of the best examples of substance that is hydrophobic which canÕt mix or dissolve with water. It is highly hydrophobic because the interaction in oil is more compact than other compounds.
Hydrophobic molecules do not come in contact with water; they "fear" water (root word, phobic). Hydrophilic molecules, on the other hand, do come in contact with water; they "love" water (root word, philic). [hydro means water]
Ions cannot diffuse through a phospholipid bilayer because they are not able to dissolve in lipids, hence the phosphoLIPID bilayer . Also, since they have an electrical charge, they are repelled by the membrane.
no, that would mean water molecules are not attracted to other water molecules
Hydrophobic Repelling, resists being combined with, or unable to dissolve in water. your wording is strange since a hydrophobic molecule repels water and not the other way around, water does not repel a hydrophobic molecule.
Lipids are hydrophobic. This quality means that they repel water rather than draw it in.

All Lipids are hydrophobic: that's the one property they have in common. This group of molecules includes fats and oils, waxes, phospholipids, steroids and cholesterol.
Lipids are hydrophobic or ambiphilic small molecules. In water, hydrophobic lipids such as oils and fats clump up and separate from the water. In water, ambiphilic lipids such as phospholipids form bilayer structures; the body of living creatures uses these bilayer structures to form cell membranes and vesicles.
Lipids are different from other macromolecules because they are hydrophobic and don't dissolve in water.
Cholesterol molecules are considered to be lipids since they are a class of steroids which are lipids. Cholesterol is hydrophobic due to its hydrocarbon composition; this is a commonality within lipids.
Lipids are broadly defined as molecules that are hydrophobic (insoluble in water) or ampiphilic (possessing both hydrophobic and hydrophilic properties). Phospholipids are a subgroup of ampiphilic lipids which contain a negatively charged phosphate group.
Lipid molecules are hydrophobic because they consist of long carbon-hydrocarbon backbones and contain only a small amount of oxygen.
Hydrophobic molecules do not dissolve in water. This is because water is hydrophilic. Another way to say this is that lipids, which are nonpolar, cannot dissolve in water, which in polar.
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=)
No. Hydrophobic is a concept or symptom, not a substance as lipids are.
There are a great many kinds of lipids see the Sources and related links below. Lipids may be broadly defined as hydrophobic or amphiphilic small molecules.
