Lecithins 64-72 apolipoprotein A4 Homo sapiens 41-49 2211707-6 1990 We conclude that apoA-IV-2 has more alpha-helical structure, is more stable in solution, and is more hydrophobic than apoA-IV-1, and that these distinctive structural features are associated with a higher affinity for phospholipid surfaces and an increased catalytic efficiency of lecithin:cholesterol acyltransferase activation.
