isolation from tear samples in sufficient quantities is a tedious task. To provide access to these species in their pure form, and to shed light on their properties, we here report a general strategy for the synthesis and structural characterization of these lipid classes. In addition, we study the organization and behavior of the lipids at the air–tear interface. Through these studies, new insights
覆盖眼表的泪膜脂质层 (TFLL) 包含几种独特的脂质类别,包括O-酰基-ω-羟基脂肪酸、I-St型二酯和II型二酯。虽然 TFLL 代表了一种独特的生物屏障,在稳定整个泪膜方面起着核心作用,但对单个脂质种类的特性和作用知之甚少。这是因为将它们从足够数量的泪液样本中分离出来是一项繁琐的任务。为了以纯形式获得这些物种,并阐明它们的特性,我们在此报告了这些脂质类别的合成和结构表征的一般策略。此外,我们研究了空气-撕裂界面处脂质的组织和行为。通过这些研究,对结构特征(如双键数量和链长)与薄膜特性(如延展性和抗蒸发性)之间关系的新见解,
