Common Fatty Acids
Saturated:: 12, +2, +2, +2 = a fatty has a LiMP (Lauric, Myristic, Palmitic, Stearic). a Dozen signifies it starts at 12, fatties = fatty acids, row meaning they grow by 2s…
A dozen fatties in a row,
always LiMP as they go.
Stearic acid: Stearic, Oleic, Linoleic, Linolenic:::
Winning! Olé! The more Lens wins the stearing contest. (= stearic, but if unsaturated forms base Oleic. Each successive “Lin/Len” gains another double bond at the next farthest non-conjugated position.)
Unsaturated: “Olé! A double-bonded oyl at 9:00 o’clock!” (all unsaturated fats, ( ~ oils), have a Delta double-bond at the 9th position, and all the acyl group names end in “oyl”.
Arachidonic acid: Best: Spiders form webs, which spiral outward. To make a complete spiral, remember that it would take 4 cis bends to bring the chain back to its beginning if they were all flattened out. OR “Call 911, for (4) 5 arachnids ate (8) 11 teens(14)! (4 double bonds, at 5, 8,(yah, I know the 9 of 911 doesn’t help. whoops. Maybe just “spiders have 8 legs”.. The largest fatty (20) ate for…
