Editing Very low-density lipoprotein (section)

==Physical properties==
Very-low-density lipoprotein size is variable, with diameters ranging from approximately 35 to 70&nbsp;nm.<ref name=packardandshepherd1997>{{cite journal|vauthors=Packard CJ, Shepherd J|year=1997|title=Lipoprotein Heterogeneity and Apolipoprotein B Metabolism|journal=Arteriosclerosis, Thrombosis, and Vascular Biology|volume=17|issue=12|pages=3542–3556|doi=10.1161/01.atv.17.12.3542|pmid=9437204}}</ref>  Some researchers further classify VLDL particles into VLDL1 and VLDL2 based on size (as measured by [[Svedberg]] flotation units), where VLDL1 particles are larger and contain more triglycerides, while other researchers create a tripartite system by subdividing VLDL1 into larger VLDL1 and smaller VLDL2 and relabeling VLDL2 as VLDL3.<ref name=packardandshepherd1997/>
