Cholesterol Prof Mamoun Ahram Resources This lecture Lippincotts Biochemistry Ch 17 Cholesterol in the body The balance between cholesterol influx and efflux is not precise resulting in a gradual deposition of cholesterol in the tissues particularly in the endothelial linings of blood vessels. 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. :. . 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. . 3.4 What Are Lipids?. 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. Lipid chemistry . Lipid chemistry . Definition . Fats and Oils (triglyceride) . Waxes. Steroids. Fat- soluble vitamins. Phospholipid. Mono- di glycerides . Lipid compounds including: . Classification of Lipids. Pratt & . Cornely. , . Ch. 8. Lipids and Membranes. There is a lot of important biochemistry of lipids.. We won’t cover it all!. The key points for this class have to do with their role in membranes and fat metabolism. Beheading. Learning Objective: . To learn why Henry VIII beheaded some of his wives..

What are two ways organisms can obtain their energy?. Lipids are hydrophobic or amphipathic small molecules that may originate entirely or in part by carbanion-based condensations of thioesters (fatty acids, polyketides, etc.) and/or by carbocation-based condensations of isoprene units . Cholesterol. Rich in hydrocarbon. Polar group (usually small). Oleic acid. Lipids serve a wide variety of functions. Vitamin K. Surfactants. Protection. Membrane. components. Insulation.
