Grease is non-polar - vaseline, oil, wax - they are all hydrocarbons, with bonds that aren't polar. To remove a grease from your hands you need a non-polar solvent, not water.

Small nonpolar hydrophobic molecules such as fatty acids?
Small, nonpolarn hydrophobic molecules such as fatty acids easily pass through a membrane's lipid bilayer.
What are the monomers of triglyceride?
1 glycerol and 3 fatty acids so the monomers basically are glycerol and fatty acids
Are essential fatty acids polyunsaturated fatty acids?
Yes, and also monounsaturated fatty acids. The saturated fat is the bad fat.
What group of organic compounds contain fatty acids?
Fatty acids contain carboxyl groups. The functional group of fatty acids is -COOH. There are 2 types of fatty acids called saturated and non saturated.
How do you separate amino acids from fatty acids?
Amino acids are soluble in water and fatty acids are not.
What is nonpolar component of triglycerides?
The fatty acids of a triglyceride are nonpolar.
What is the nonpolar end of a fatty acid?
amino acids
Which molecule prevents cell membrane from dissolving in water?
Nonpolar Fatty Acids
Small nonpolar hydrophobic molecules such as fatty acids?
Small, nonpolarn hydrophobic molecules such as fatty acids easily pass through a membrane's lipid bilayer.
What part of the cell membrane prevents the cell from dissolving in water?
Nonpolar Fatty acid chains
Which part of the membrane prevents organisms from dissolving in water?
Nonpolar fatty acid chains.Non fatty acid chains
Which part of the cell membrane non-polar and prevents the cell from dissolving?
Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
Are fats amphipathic?
Yes. The glycerol head is polar while the fatty acids are nonpolar. Thus, fat is indeed amphipathic.
What type of bonding do lipids have?
The type of chemical bonds for lipids are nonpolar C-H bonds. The actual bonds that attach the fatty acids to the glycerol are refered to as ester linkages
Which part of the cell membrane prevent organisms from dissolving in water?
Nonpolar fatty acid chains.Non fatty acid chains
What is the most common building blocks of lipids?
Fatty acids and glycerol
Distinguish between saturated fatty acids and saturated fatty acids?
There is no difference between saturated fatty acids and saturated fatty acids. If you meant saturated fatty acids and UNsaturated fatty acids, then the unsaturated ones are the ones with double (or, theoretically, triple) bonds in the carbon chain.
