Water is polar, but lipids are nonpolar.
The lipid bilayer prevents the cell from dissolving in water.
When a lipid is mixed with water, the lipid molecules will form structures such as micelles or lipid bilayers due to their hydrophobic tails being shielded from the water by their hydrophilic heads. This is because lipids are amphipathic molecules with both hydrophobic and hydrophilic regions.
The lipid bilayer of the cell membrane is hydrophobic, composed of fatty acid tails that repel water molecules. This hydrophobic core provides a barrier that prevents water-soluble molecules from freely passing through the membrane.
No.they do not mix with water.
The tonoplast, a membrane surrounding the vacuole, acts as a barrier that prevents the mixing of vacuole contents with the cytoplasm. This membrane is selectively permeable, allowing only certain molecules to pass in and out of the vacuole. Additionally, the acidic nature of the vacuole helps maintain a pH gradient that discourages mixing with the cytoplasm.

Nonpolar Fatty acid chains
To prevent protein powder clumps when mixing it in hot water, try mixing the powder with a small amount of cold water first to create a smooth paste, then gradually add the hot water while stirring continuously. This method helps the protein powder dissolve more evenly and prevents clumping.

You should never fill the mixing bowl beyond two-thirds full. This allows space for ingredients to expand and prevents spillage during mixing. Additionally, leaving room helps ensure thorough mixing and prevents messes that can occur when the bowl is too full.
i dont know and dont CARE
Water is polar, but lipids are nonpolar.
The general equation for the hydrolysis of a lipid molecule is: Lipid + water → fatty acid(s) + glycerol
Yes, carbon disulfide (CS2) is insoluble in water because it is a nonpolar covalent compound and water is a polar solvent. The difference in polarity between the two substances prevents them from mixing or dissolving in each other.

Yes, water can cross the lipid bilayer through a process called simple diffusion.
