PPT-17.2 Fatty Acids We might think of saturated fatty acids as chips with regular shapes

Similarly irregularly shaped chips would be like unsaturated fatty acids that do not fit closely together Learning Goal Draw the condensed or lineangle structural formula for a fatty acid and identify it as saturated or unsaturated. 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-II. Fatty Acids . can be classified to:. A-. S. aturated Fatty Acids:. Fatty . acids . have . no double bonds ,side . chain . are (alkane. ).. 1)Short chain:. From 4 to 10 Carbon atoms ,and present as liquid in room Temp. . Triacylglycerols. Many soft margarines, stick margarines, and solid shortenings are produced by the partial hydrogenation of vegetable oils.. Learning . Goal . Draw . the condensed or line-angle structural formula for the products of a triacylglycerol that undergoes hydrogenation, hydrolysis, or saponification.. Derived lipids .. They are substances that are soluble in lipid or derived from the lipids by hydrolysis; for examples, cholesterol and fat soluble vitamins.. Fatty Acids . Classification. a-saturated . Triacylglycerols. Many soft margarines, stick margarines, and solid shortenings are produced by the partial hydrogenation of vegetable oils.. Learning Goal . Draw the condensed structural formula for the product of a triacylglycerol that undergoes hydrogenation, hydrolysis, or saponification.. A-Saturated 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 . properties in food products . Fatty a. cids. Fats are composed of fatty acids and glycerol. . A . fatty acid is made up of a chain of carbon atoms, with a methyl group at one end and an acid group at the . Lipids. Category of compounds that includes. Triglycerides. Sterols. Phospholipids. Contain carbon, oxygen, and hydrogen. Hydrophobic. Lipids. Basic functions in the body. Store and provide energy. Fats provide 9 kcal per gram. Natural waxes are found on the surface of fruits and on the leaves and stems of plants, where they help prevent loss of water and damage from pests.. Waxes on the skin, fur, and feathers of animals provide a waterproof coating.. Food is eaten and digested in the body to allow the absorption of energy and nutrients.. There . are two different types of nutrients:. macronutrients;. micronutrients.. Macronutrients . provide energy and these include:. Acids & . Eicosanoids. BIOMEDICAL IMPORTANCE. Unsaturated fatty acids in phospholipids of the cell. membrane are important in maintaining membrane. fluidity. A high ratio of polyunsaturated fatty acids to. Which dietary fats are available?Fats that are suitable for feeding animals are and sunower – or in the tropics such as palm of their special fatty acids. Fish oils, which feeds is to enrich LIPIDS Lipids are heterogeneous group of molecules related to fatty acids . They are hydrophobic and are characterized by sparing solubility inwater but high solubility in non - polar solvents su P. eaneus. monodon. ). AINA OLUWAGBENGA EMMANUEL. DEPARTMENT OF FISHERIES, .
