近年来不少作者提出高密度脂蛋白(HDL)在脂质代谢,特别是由外周组织将胆固醇运转到肝脏进行分解代谢中,可能起到重要作用。虽然对这些生理功能的机理,尚不十分清楚,但显然与HDL中载脂蛋白有密切关系。因此研究载脂蛋白的结构与功能有助于阐明上述问题。前文已报道鸭血清HDL的大量分离和纯化、本文介绍其中载脂蛋白的分离,提纯及其某些性质的研究。 In recent years, many authors have suggested that high-density lipoprotein (HDL) may play an important role in lipid metabolism, especially in the catabolism of cholesterol to the liver by peripheral tissues. Although the mechanisms of these physiological functions are not well understood, they are clearly linked to apolipoproteins in HDL. Therefore, the study of the structure and function of apolipoprotein helps to clarify the above problems. The previous article has reported a large number of duck serum HDL isolation and purification, this article describes the apolipoprotein separation, purification and some of its properties.
