Now, to demonstrate what types of disaccharides we can have and the types of Oglycocitic bonds that we can have in nature, let's take a look at the three most common types of disaccharide. So, these are maltose, lactose, and sucrose. So let's begin with maltose. And this is what a single maltose disaccharide actually looks like. So, a maltose disaccharide consists of an alpha D glucose in its cyclic form, bound to another alpha D glucose, also in its cyclic form. And the binding takes place between carbon number one of the first glucose and carbon number four of the second glucose.
