In this video, we're discussing a triacylglycerol reaction in the form of oxidation. Now, under this type of reaction, we're going to say that elemental oxygen O2, cleaves pi bonds to create carboxylic acids. So, if we take a look here, here go our pi bonds in our original triglyceride molecule. And if we look at them, what's going to happen here is we're using atmospheric oxygen, elemental oxygen. It's going to cleave these pi bonds. And here, just for color coding, these three double-bonded carbons are these three double-bonded carbons. And then these three would be these three. I basically just cut them apart from each other. They still have their double bonds, but we're trying to make carboxylic acids now. So these carbons to make carboxylic acid, they're each going to double bond to oxygen. And to make it a carboxylic acid, they'll also be connected to an OH group. And the same thing on the other side. So in that way, we created carboxylic acids from our original double-bonded carbons. So that's the basis of this reaction. We're using environmental oxygen and atmospheric oxygen O2 to cut or cleave the pi bond in order to create two carboxylic acids from the place where it's cut, the pi bond that's cut. So just keep this in mind when dealing with the oxidation of a triacylglycerol or a triglyceride molecule.
