自70年代末作者发现北京鸭和树鼩均富含高密度脂蛋白(HDL),以高胆固醇膳食饲养不易形成动脉粥样硬化(AS),首次为国际上提出的HDL有抗AS作用提供了实验依据和研究其抗AS机理的模型。apo A-I是HDL中的主要载脂蛋白,具有多种功能,因此研究鸭apo A-I的一级结构有助于阐明 Since the late 1970s, the authors found that both Beijing duck and tree shrew are rich in high density lipoprotein (HDL) and are not susceptible to atherosclerosis (AS) in high-cholesterol diets, providing for the first time an internationally proposed anti-AS effect of HDL Experimental basis and study of its anti-AS mechanism model. apo A-I is a major apolipoprotein in HDL and has multiple functions, so studying the primary structure of duck apo A-I helps to elucidate
