This review focuses on some new techniques to study the behavior of peptides and proteins bound to oil droplets. We will show how model peptides e.g., amphipathic alpha helices (AalphaH) and amphipathic beta strand (AbetaS) and some apolipoproteins adsorb to triacylglycerol (TAG) droplets and how they behave once adsorbed to the interface. While most of the studies described involve peptides and proteins at an oil/water interface, studies can also be carried out when the surface has been partially covered with phospholipids. This work is important because it examines biophysical changes that take place at lipid droplet interfaces and how this may relate to the metabolism of lipoproteins and lipid droplets.
本综述聚焦于一些研究与油滴结合的肽和蛋白质行为的新技术。我们将展示模型肽,如两亲性α螺旋(AalphaH)、两亲性β链(AbetaS)以及一些载脂蛋白如何吸附到三酰甘油(TAG)油滴上,以及它们吸附到界面后会有怎样的行为。虽然所描述的大多数研究涉及油/水界面处的肽和蛋白质,但当表面已部分被磷脂覆盖时也可开展研究。这项工作很重要,因为它研究了脂质小滴界面发生的生物物理变化,以及这可能如何与脂蛋白和脂质小滴的代谢相关。
