Now, what's the big deal about betappleted sheets? Well, because we have a high content of beta pleated sheets these molecules will have a high potential will have a high propensity of binding to other molecules that also contain beta pleated sheets. Why is that? Well, recall that the structure of the beta pleated sheet consists of these linear polymers of amino acid. So we have one linear polymer of amino acid, a second linear polymer stacked on top of one another, a third one stacked on top, stacked on top of that and so forth. So these beta pleated sheets consist of these linear polymers stacked on top of one another.
