4. Aldehydes, in particular 3,6-Nonadienal, are a dominant product of the oxidation of linolenic acid. Show the steps in the formation of the aldehyde from the auto-oxidation of linolenic acid. Note that the major hydroperoxides formed by autoxidation of linolenic acid are 9-ROOH, 12-ROOH, 13-ROOH, 16- ROOH and 16-ROOH.

**Formation of Aldehydes from Linolenic Acid**

Aldehydes, particularly 3,6-Nonadienal, are prominent products from the oxidation of linolenic acid. The following highlights the steps involved in forming these aldehydes through the auto-oxidation process of linolenic acid. It is important to note that the major hydroperoxides formed during this process are 9-ROOH, 12-ROOH, 13-ROOH, 16-ROOH, and 16-ROOH.

**Chemical Diagram Explanation**

The diagram shows the molecular structure of linolenic acid, with specific bonds and atoms labeled:
- **HO:** Represents the hydroxyl group at the beginning of the carbon chain.
- The carbon chain contains multiple double bonds, indicated by the marked positions 9, 12, and 15 (in blue), corresponding to the location of double bonds within the carbon chain.
- Positions 3, 6, 9, and 12 are indicated in red, showing areas of interest for autoxidation and hydroperoxide formation.
