well im not 100% sure, but i know that water is polar, and only other polar things can dissolve into it. fats, i.e. cholesterol, are not soluble in water, and therefore must be nonpolar. ALSO, cholesterol is made up of four hydrocarbon rings. hydrocarbon rings, obviously, are made of hydrogen and carbon. (side note - polar compounds are formed when the difference of electromagnetivity - how much the element attracts electrons - between the elements causes an imbalance in the direction of attraction). the difference in electromagnetivity between those two elements is too little to be considered a polar molecule.

Is dibrominated cholesterol more polar than cholesterol?
Yes, dibrominated cholesterol is more polar than cholesterol due to the addition of bromine atoms which increase the molecule's polarity. The bromine atoms can form stronger interactions with polar solvents compared to cholesterol.
What are the polar groups in cholesterol?
There is only one polar group that can be found in cholesterol despite it being nonpolar. That one group is a hydroxyl group.
Is cholesterol more soluble in water or hexane?
Hexane is a non-polar chain hydrocarbon; on the principle of "like dissolves like" hexane will dissolve other non-polar compounds quite well. Water is a polar molecule, as are all halogens as exemplified by the simplest common halogen of all, hydrochloric acid. Halogen acids, common refrigerants, even some anesthetics are all polar molecules and therefore dissolve fairly well in other polar liquids, including water.
What is the effect of acetone on the solubility of cholesterol?
Acetone can increase the solubility of cholesterol by dissolving it more effectively. This is because acetone is a polar solvent that can interact with the cholesterol molecules, helping them to dissolve more easily.
Is the cholesterol located between the fatty acid chains polar or nonpolar?
Cholesterol, which is often found embedded between the fatty acid chains of the phospholipid bilayer in cell membranes, is largely nonpolar with a small polar region. Here's why: Nonpolar Region: Cholesterol consists of a hydrocarbon tail and a bulky steroid ring structure, both of which are nonpolar. These parts interact well with the nonpolar fatty acid chains of the membrane lipids. Polar Region: Cholesterol has a small hydroxyl group (-OH) at one end, which is polar. This polar group tends to interact with the polar heads of the phospholipids or the aqueous environment. In summary, cholesterol is primarily nonpolar, but it has a minor polar component that allows it to interact with both polar and nonpolar parts of the cell membrane, helping to stabilize its structure.

Why do marine organisms living in polar regions have a very high proportion of cholesterol in their membrane?
Marine organisms living in polar regions have a very high proportion of cholesterol in membranes to keep the membranes more fluid and keep the molecules moving faster because in cold temperature, molecules move slower.
Is the cholesterol molecule mostly non polar or polar and why?
It is MOSTLY non polar because it has 27 carbons arranged in several ring structures, and a side chain. This makes it non polar. The only polar parts of the molecule is an -OH group on one of the ring structures.
Why is one end of the phospholipids polar and the other nonpolar?
what is a potential danger of excess cholesterol in the human body
What are non polar molecules that include fats oils and cholesterol?
Non-polar molecules such as fats, oils, and cholesterol are hydrophobic molecules that consist mostly of carbon and hydrogen atoms. These molecules do not have a significant electric charge distribution, making them insoluble in water but soluble in nonpolar solvents.
Why does marine organism living in polar regions have high proportion of cholesterol in their membrane?
Marine organisms living in polar regions have a very high proportion of cholesterol in membranes to keep the membranes more fluid and keep the molecules moving faster because in cold temperature, molecules move slower.
Which is more polar cholesterol or cholesteryl acetate?
As you can see here this is the equation of acetic and stearic acid.it shows how they are different from each other. This is because acetic acid reacts much more exp[losively with water.
Can steriods and cholesterol cross the cell membrane on their own?
Yes because the cell membrane allows non polar molecules through
