PPT-Lipids are hydrophobic, nonpolar organic molecules.

They are insoluble in water and highly soluble in one or more of the following solvents ether chloroform benzene and acetone Make up about 5 from organic substances which enter in the structure of living cell . Lipids . do not form true polymers. The unifying feature of lipids is having little or no affinity for water. Lipids are hydrophobic because they consist mostly . of hydrocarbons, which form nonpolar covalent bonds. Nature’s flavor enhancer. lipids vs carbohydrates. - . both .
