Some transmembrane proteolipids, especially those found in bacteria, are referred to as lipoproteins; they are not related to the lipoprotein particles that this article is about. Such transmembrane proteins are difficult to isolate, as they bind tightly to the lipid membrane, often require lipids to display the proper structure, and can be water-insoluble. Detergents are usually required to isolate transmembrane lipoproteins from their associated biological membranes.
