Munther Lipids Lipids are compounds that are insoluble in water but soluble in an organic solvent eg ether benzene acetone chloroform lipid composed mainly from C H O The main feature in all lipids is the large number of carbonhydrogen bonds which makes them . Lipids are….. It can be defined as . nonpolar. organic compound insoluble in polar solvent , but . soluble in organic solvents. such as benzene ,ether, . chloroform.. Biological role of lipids. :. Chapter 29. 2. Lipids. are . biomolecules. that are soluble in organic solvents.. The identity of lipids is defined on the basis of a physical property and not by the presence of a particular functional group.. . 2003-2004. Lipids. 2003-2004.

Lipids are relatively insoluble in water.. They are soluble in . nonpolar. solvents such as chloroform , diethyl ether, acetone, benzene and ether.. The hydrophobic (water hating) nature of lipids is due to the predominance of hydrocarbon chain.(-CH2-CH2-CH2-) in their structure. Fats and Oils. Classification of Nutrients. Carbohydrates.

Lipids. are a diverse group of molecules that contain regions composed almost entirely of hydrogen and carbon. All lipids contain large chains of nonpolar hydrocarbons. Most lipids are therefore hydrophobic and water insoluble. We have touched on their metabolism.. Now we will wrap that up a bit by describing once you have digested carbohydrates, lipids, and proteins, what does your body do with it.. Metabolism. Metabolism:.
