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.

∙ 13y agoLipids 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)

∙ 9y agoYes there are hydrogen bonds between cholesterol and phospholipid molecules. These bonds are better known as hydrogen-bonded water bridges.

What is hydrophobic compound?
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.
What is the difference between hydrophillic and hydrophobic molecules?
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]
Why cant polar molecules and ions diffuse across the cell membrane?
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.
Is water hydrophobic?
no, that would mean water molecules are not attracted to other water molecules
Do hydrophobic molecules dissolve in water?
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.
Are lipids hydrophobic or hydrophilic?
Lipids are hydrophobic. This quality means that they repel water rather than draw it in.
What types of molecules are hydrophobic?
lipidsLipids
Are lipids hydrophobic or hydrophobic?
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.
Are lipids similar to water molecules?
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 differ from other large biological molecules in that they?
Lipids are different from other macromolecules because they are hydrophobic and don't dissolve in water.
What group of macromolecules does cholesterol belong?
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.
What is lipids or fats?
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.
What specific chemical property makes lipids hydrophobic?
Lipid molecules are hydrophobic because they consist of long carbon-hydrocarbon backbones and contain only a small amount of oxygen.
What do molecules do in water?
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.
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=)
Is hydrophobic a lipid?
No. Hydrophobic is a concept or symptom, not a substance as lipids are.
What is the structal formula for a lipid?
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.
