Triglycerides And Fatty Acids

  1. 1. Triglycerides and Fatty Acids Katie and Taz
  2. 2. Structure of Fatty Acids <ul><li>Fatty acids can be either saturated or unsaturated </li></ul><ul><ul><li>Saturated being without multiple bonds </li></ul></ul><ul><ul><li>Unsaturated being with multiple bonds </li></ul></ul><ul><li>They are the products of broken down fats </li></ul>Stearic acid Linoleic acid
  3. 3. Sources of Fatty Acids <ul><li>Butterfat </li></ul><ul><li>Coconut oil </li></ul><ul><li>Palm oil </li></ul><ul><li>Animal fats </li></ul><ul><li>Olive oil </li></ul><ul><li>Rapeseed oil </li></ul><ul><li>Fish oil </li></ul><ul><li>Liver fats </li></ul><ul><li>Peanut oil </li></ul><ul><li>Grape seed oil </li></ul>Fatty acids are obtained from natural oils and fats
  4. 4. Triglycerides <ul><li>Are triesters where the alcohol glycerol is esterified with 3 fatty acids </li></ul>left part : glycerol right part from top to bottom : palmitic acid oleic acid, alpha-linolenic acid
  5. 5. Saponification <ul><li>The hydrolysis of triglyceride esters, which produces soaps (the salt of the fatty acid) </li></ul><ul><li>A metallic base reacts with a fat or oil </li></ul><ul><li>If NaOH is used a hard soap is formed </li></ul><ul><li>If KOH is used a soft soap is formed </li></ul><ul><li>Soaps are usually a mixture of triglycerides and their quality depends on the oil or fat used to make it </li></ul>
