Lipids are insoluble in water because they are

A

Neutral

B

Zwitter ions

C

Hydrophobic

D

Hydrophilic

Dear student 

Lipids are non-polar molecules while water is polar molecule, so there is no way for water to attach to a lipid molecule. Instead, the non-polar lipids will bind to themselves, which is why oils and fats form droplets on the surface of water.So, Lipids are hydrophobic means water hating. 

Good Luck 

ANSWER
Lipids are hydrophobic (water repelling) and non-polar. Non-polar substances, for instance fats and oils cannot be dissolved in water because they have made up of only carbon-carbon and hydrogen-carbon bonds. Only polar solutes dissolve in polar solvents.
So, the correct option is 'Hydrophobic'.Lipids are insoluble in water because they are A Neutral B Zwitter ions C Hydrophobic D Hydrophili
