Triacylglycerol Reactions: Hydrolysis
Multiple Choice
The salt of a fatty acid has its ending of “ic acid” changed to “ate”. Based on this information provide the name of the salt created from the following saponification reaction.
A
Potassium Laurate
B
Sodium Oleate
C
Potassium Myristate
D
Potassium Lactate
0 Comments
Verified step by step guidance1
Identify the structure of the triglyceride in the image. It consists of three fatty acid chains esterified to a glycerol backbone.
Recognize that saponification involves the hydrolysis of the ester bonds in the triglyceride using a strong base, such as KOH, to form glycerol and the potassium salts of the fatty acids.
Determine the length of each fatty acid chain in the triglyceride. Count the number of carbon atoms in one of the fatty acid chains shown in the image.
Convert the name of the fatty acid from its 'ic acid' form to its 'ate' form. For example, if the fatty acid is myristic acid, the salt formed would be potassium myristate.
Based on the structure and the number of carbon atoms in the fatty acid chain, identify the correct name of the salt formed in the saponification reaction.
