===Transmembrane lipoproteins===
Some transmembrane [[proteolipid]]s, especially those found in [[bacteria]], are referred to as lipoproteins; they are not related to the lipoprotein particles that this article is about.<ref name=bact>{{cite web |title=Microbial Proteolipids and Lipopeptides - glycopeptidolipids, surfactin, iturnins, polymyxins, daptomycin |url=http://www.lipidhome.co.uk/lipids/simple/lipopep/index.htm |website=The LipidWeb |access-date=21 July 2019}}</ref> Such [[transmembrane protein]]s 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.
