Phospholipids are the type of molecules that prevent cell membranes from dissolving in water. They have a hydrophilic (water-attracting) "head" and two hydrophobic (water-repelling) "tails." This unique structure allows them to form a bilayer, with the hydrophobic tails facing inward and the hydrophilic heads facing outward, creating a barrier that protects the cell's interior from the surrounding aqueous environment. This arrangement is crucial for maintaining the integrity and functionality of the cell membrane.

Which molecule prevents cell membrane from dissolving in water?
Nonpolar Fatty Acids
What part of the cell membrane prevents organisms from dissolving organisms from dissolving in water?
The lipid bilayer prevents the cell from dissolving in water.
Why does water not dissolve motor oil?
Water and motor oil are immiscible because they have different polarities. Water is a polar molecule, while motor oil is nonpolar. This difference in polarity prevents water from dissolving motor oil.
Which molecule keeps hydrophilic molecules from easily crossing cell membranes?
The molecule that keeps hydrophilic molecules from easily crossing cell membranes is phospholipids. Cell membranes are primarily composed of a phospholipid bilayer, which has hydrophobic (water-repelling) interior regions that act as a barrier to polar and charged substances. This hydrophobic nature prevents hydrophilic molecules from freely diffusing through the membrane, requiring specific transport proteins or channels for passage.
Does polythene dissolve in water?
No, polythene does not dissolve in water as it is a non-polar polymer and water is a polar solvent. This lack of attraction between the polythene molecules and water molecules prevents it from dissolving.
What part of the cell membranes prevents the cell from dissolving water?

Why is butane not soluble in water?
Butane is a nonpolar molecule, while water is a polar molecule. Nonpolar molecules like butane are not attracted to the polar water molecules, making it insoluble in water. This lack of interaction between the molecules prevents butane from dissolving in water.
Why does water not dissolve motor oil?
Water and motor oil are immiscible because they have different polarities. Water is a polar molecule, while motor oil is nonpolar. This difference in polarity prevents water from dissolving motor oil.

What is a type of molecule that interact with water by dissolving in water and or forming hydrogen bonds with water molecules?
hydrophilic
Why chloroform not soluble in water?
Chloroform is not soluble in water because it is a nonpolar molecule, while water is a polar molecule. Polar substances like water tend to dissolve in other polar substances, and nonpolar substances like chloroform tend to dissolve in other nonpolar substances. This difference in polarity prevents chloroform from effectively mixing or dissolving in water.

The process of breaking apart two bonds with water is called?
When certain molecular crystals are added to water, they are able to dissolve and break down into their original molecules, if they are affected by the interatomic hydrogen bonds that water induces. A simple answer: dissolving.
