So fructose we typically obtain from plants, and galactose we typically obtain from milk or dairy products. Now, it turns out that unlike glucose, which actually has its own catabolic pathway in our cells, these two sugars do not have their own individual breakdown pathways. And so when these two sugars monosaccharides actually make their way into the cells of our body, these sugars must be transformed into molecules, into metabolites that are part of that glycolytic pathway. And once that happens, we can basically incorporate those glycolytic metabolites into the glycolytic pathway. So let's begin by discussing fructose. Now, depending on what type of cell that fructose actually ends up, it can be converted into a glycolytic metabolite in one of two ways.
