PPT-Digestion Of Lipids Action Of

Specific Lipid Digesting Enzymes in Small Intestine Digestion of Lipids is cleavage of Ester bonds present in their structures Dietary forms of Lipids are digested By action . 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.. 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. . 2003-2004. Lipids. 2003-2004. Large biomolecules that are made mostly of carbon and hydrogen with a small amount of oxygen (sometimes Phosphorous).. Lipids . Monomer subunits . Glycerol and 3 fatty acids. 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.. Learn the structure of a . phospholipid. .. Learn how lipids are tested for.. What is a lipid?. Like most other biochemical substances, lipids contain . Pratt & . Cornely. , . Ch. 8.
