Question

Given the following lipids, predict the results for the Solubility and Bromine Tests for various types of lipids. Enter your predictions for each What type of lipid? Fatty Acid, Triacylglycerol, Glycerophospholipid, Wax or Steroid Will the lipid be soluble in Water? Yes or No Will the lipid be soluble in CH,CI,? Yes or No . In the Bromine Test, bromine adds to carbon-carbon double bonds in carbon chains. If the bromine reacts, the red-orange color will fade. For each, will the color Fade Rapidly or Persist? Is the lipid have carbon-carbon bonds Saturated or Unsaturated? Solubility Color Fades Soluble Lipid Туре Saturation in CH2CI Rapidly/Persists in Water Steric Acid Oleic Acid Olive Oil Safflower Oil Lecithin Cholesterol Propanoic Acid Palmitoleic Acid Testosterone Beeswax 1. Write the CONDENSED STRUCTURAL FORMULAS for the esterification reaction of glycerol and three butanoic acids
