Please draw a mechanism for the formation of propanal from the oxidation of C18:3 (linolenic acid). Show the pathway for the formation of lipid peroxide and the breakdown of the peroxide via B-scission. I am not interested in side reactions.

We cannot add pictures/links in this jiska website. Sorry
okay, is there any written guidance that you can give me although?
Sure I could give you some tips/ and some information:
Linolenic acid is a type of fatty acid. It can refer to either of two octadecatrienoic acids (i.e. with an 18-carbon chain and three double bonds, which are found in the cis configuration), or a mixture of the two.
Mechanism of lipid peroxidation.
Lipid peroxidation is the oxidative degradation of lipids. It is the process in which free radicals "steal" electrons from the lipids in cell membranes, resulting in cell damage. This process proceeds by a free radical chain reaction mechanism. It most often affects polyunsaturated fatty acids, because they contain multiple double bonds in between which lie methylene bridges (-CH2-) that possess especially reactive hydrogen atoms. As with any radical reaction, the reaction consists of three major steps: initiation, propagation, and termination. The chemical products of this oxidation are known as lipid peroxides or lipid oxidation products (LOPs).

Minimize the number of slides.
To maintain a clear message and to keep your audience attentive and interested, keep the number of slides in your presentation to a minimum.
Choose a font style that your audience can read from a distance.
Choosing the right font style, such as Helvetica or Arial, helps to get your message across. Avoid narrow fonts, such as Arial Narrow, and avoid fonts that include fancy edges, such as Times.
To learn more about how you can use pre-designed theme fonts in your presentation, see All about themes, Quick Styles, cell styles, and background styles.
Choose a font size that your audience can read from a distance.
Choosing the right font size helps to get your message across.
Note: The following measurements indicate the size of a font on your computer screen, not projected on a screen for your audience in full screen mode. To enable full screen mode, on the View tab, in the Presentation Views group, click Slide Show.
A one-inch letter is readable from 10 feet.
A two-inch letter is readable from 20 feet.
A three-inch letter is readable from 30 feet.

Keep your text simple by using bullet points or short sentences.
Use bullets or short sentences, and try to keep each to one line; that is, without text wrapping.
You want your audience to listen to you present your information, rather than read the screen.
Some projectors crop slides at the edges, so long sentences may be cropped.
You can remove articles such as "a" and "the" to help reduce the word count on a line.
Use art to help convey your message.
Use graphics to help tell your story. Don't overwhelm your audience by adding too many graphics to a slide, however.
Make labels for charts and graphs understandable.
Use only enough text to make label elements in a chart or graph comprehensible.
Make slide backgrounds subtle and keep them consistent.
Choose an appealing, consistent template or theme that is not too eye-catching. You don't want the background or design to detract from your message.
For more information about using themes, see Add color and design to my slides with themes.
Use high contrast between background color and text color.
Themes automatically set the contrast between a light background with dark colored text or dark background with light colored text.
