Now, I'd like to briefly focus on a topic known as lactose intolerance. Now, lactose is a disaccharide sugar molecule and what that means is it actually consists of two individual monosaccharides. One of them is galactose and the other one is glucose. And these are connected by a special type of bond known as the beta one four glycocitic bond. Now, these lactose molecules are found in milk products and other dairy products. So if you ingest things like cheese or ice cream or milk itself, or let's say yogurt or sour cream, all of these dairy products basically contain lactose.
