In this example, it states, "provide shorthand notations for each fatty acid." These here represent our unsaturated fatty acids. Our memory tool number 2 tells us that 16 palms occupy lovely lush 20 acres. So here, if we take a look, we have p, o, l, l, and a. Alright. So, taking a closer look, for "palms", we're referring to palmitoleic acid, which is represented as 16:1. Here we have "occupy", which is Oleic acid, where we increase the length by 2 carbons and maintain the same number of Pi Bonds, resulting in 18:1. Then here, these three are all 18 carbons, but the number of Pi Bonds increases: first 18:1, then 18:2, and then 18:3. This latter sequence includes Linoleic acid and Linolenic acid. Then we have "20 acres", which corresponds to Arachidonic acid. Here, we increase by 2 carbons to 20, and the number of Pi Bonds goes up by one more to 20:4.

We can see that we start with 16 carbons, then these three remain at 18 carbons, with an increasing number of Pi Bonds. Then we progress to 20 carbons, where the number of Pi Bonds increases by just one more to 20:4. Alright. So here, Linoleic acid is "lovely", which would be represented as 18:2. "Occupy" is Oleic acid, so this would be 18:1. Arachidonic Acid is "20 acres", so this notation is 20:4. Linolenic acid is "lush", so it's represented as 18:3. These are the shorthand notations for each of these unsaturated fatty acids.
