TGRLP from Cu-deficient rats appeared more fluid than those from controls as sensed by the fluorescence anisotropy of 1,6-diphenyl-l-3,5-hexatriene (DPH). This high fluidity was related to alow cholesterol: phospholipid ratio and high triacylglycerol content in these lipoproteins. TGRLP from Cu-deficient rats were more susceptible to<jats:italic>in vitro<\/jats:italic>peroxidation than lipoproteins from control rats as shown by the rate of diene conjugation. The damage induced by the peroxidation resulted in a more ordered state of the lipid fraction especially in lipoproteins from Cu-deficient rats. Thus, after<jats:italic>in vitro<\/jats:italic>peroxidation, TGRLP from Cu-deficient rats were more rigid than those from controls. These results suggest that Cu deficiency induces modifications in physicochemical properties of TGRLP which could affect their metabolism.<\/jats:p>","DOI":"10.1079\/bjn19960180","type":"journal-article","created":{"date-parts":[[2005,9,17]],"date-time":"2005-09-17T04:07:20Z","timestamp":1126930040000},"page":"767-773","source":"Crossref","is-referenced-by-count":5,"title":["Lipid fluidity of triacylglycerol-rich lipoproteins isolated from copper-deficient rats"],"prefix":"10.1017","volume":"75","author":[{"given":"Claude","family":"Motta","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elyett","family":"Gueux","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrzej","family":"Mazur","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yves","family":"Rayssiguier","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2007,3,9]]},"reference":[{"key":"S0007114596000803_ref015","doi-asserted-by":"publisher","DOI":"10.1016\/0003-2697(78)90586-9"},{"key":"S0007114596000803_ref017","doi-asserted-by":"publisher","DOI":"10.1097\/00041433-199210000-00002"},{"key":"S0007114596000803_ref010","doi-asserted-by":"publisher","DOI":"10.1016\/0005-2736(82)90290-5"},{"key":"S0007114596000803_ref004","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9150(83)90014-X"},{"key":"S0007114596000803_ref019","first-page":"1343","article-title":"Copper deficiency increases the susceptibility of lipoproteins and tissues to peroxidation in rats","volume":"123","author":"Rayssiguier","year":"1993","journal-title":"Journal of Nutrition"},{"key":"S0007114596000803_ref023","doi-asserted-by":"publisher","DOI":"10.1016\/0005-2760(90)90108-A"},{"key":"S0007114596000803_ref007","doi-asserted-by":"crossref","first-page":"744","DOI":"10.1016\/S0021-9258(17)32781-3","article-title":"Structure and interactions of lipids in human plasma low density lipoproteins","volume":"252","author":"Deckelbaum","year":"1977","journal-title":"Journal of Biological Chemistry"},{"key":"S0007114596000803_ref021","first-page":"1","volume-title":"Physiology of Membrane Fluidity","volume":"1","author":"Shinitzky","year":"1982"},{"key":"S0007114596000803_ref011","doi-asserted-by":"publisher","DOI":"10.1172\/JCI103182"},{"key":"S0007114596000803_ref002","doi-asserted-by":"publisher","DOI":"10.3181\/00379727-204-43640"},{"key":"S0007114596000803_ref013","doi-asserted-by":"publisher","DOI":"10.1016\/S0006-3495(79)85318-7"},{"key":"S0007114596000803_ref008","doi-asserted-by":"publisher","DOI":"10.3109\/07853899109150520"},{"key":"S0007114596000803_ref012","volume-title":"Role of Copper in Lipid Metabolism.
