Fatty Acid and Fats. What Makes Good Soap

Fatty Acids and Fats. What Makes Good Soap  

Natural fats are glycerol esters of fatty acids known as triglycerides. Unsaturated fats are generally liquids (oils) at room temperature, while triglycerides rich in saturated fatty acids are generally solids. View tristearin and triolein. Which one of these is saturated and which is unsaturated Are die double bonds in the unsaturated fat cis or transl 

Hydrolysis of animal fats in the presence of strong base leads to glycerol and salts of long-chain carboxylic acids. The latter are known as soaps . 

Detergents are closely related to soaps. They also incorporate long alkyl chains, but the carboxylate groups have been replaced by sulfonate groups (among other things). 

Compare and contrast the electrostatic potential map of a typical detergent with that of a typical soap (stearate). Which part of each molecule will be most water soluble (hydrophilic) Draw a Lewis structure that describes each molecule s water-soluble group (make sure you indicate all necessary formal charges and lone pairs). Which part(s) of each molecule will be most grease soluble (lipophilic) What kinds of atoms and bonds are found in these groups
