PPT-Lipids-II Fatty Acids can be classified to:

ASaturated Fatty Acids Fatty acids have no double bonds side chain are alkane 1 Short chain FA From 4 to 10 Carbon atoms and present as liquid in room Temp 2 Long chain FA More than 10 Carbone atoms present in . Lipids. Essential . macronutrients. Provide . energy. Building blocks for cell membranes. Form many important hormones. Help transport fat-soluble nutrients. Contribute to flavor and texture of . food. 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. Lipids are non-polar. (hydrophobic) . organic compounds, insoluble in water, . soluble in organic . solvents (ether, acetone, . carbontetrachloride. ). . They contain carbon, hydrogen, and oxygen; sometimes nitrogen and phosphorus. . Learning Objectives. Learn what a triglyceride is.. Learn what a fatty acid is..
