Verified step by step guidance1
Identify the functional groups present in linolenic acid. It is a polyunsaturated fatty acid with a carboxylic acid group at one end.
Determine the number of carbon atoms in linolenic acid. Linolenic acid has 18 carbon atoms.
Identify the positions of the double bonds. Linolenic acid has three double bonds located at the 9th, 12th, and 15th carbon atoms from the carboxyl end.
Draw the carbon chain with 18 carbon atoms, ensuring the correct placement of the double bonds at the 9th, 12th, and 15th positions.
Add the carboxylic acid group (COOH) at the end of the carbon chain to complete the structure of linolenic acid.
