In those cells, the insulin activates lipoprotein lipase, which is an enzyme that helps those adipocytes accumulate more fat molecules.

在些细胞中，胰活脂蛋白脂肪酶，一种帮助脂肪细胞堆积更多脂肪分子酶。

Saturated fat creates low-density lipoprotein, or LDL, which is the bad kind of cholesterol.

饱和脂肪会产生低密度脂蛋白，即 LDL ，是一种有害胆固醇。

But they didn't fully understand how cholesterol moves in our blood, including the roles of the different lipoproteins that ferry it around.

但他们不能理解固醇是怎么进到血液里，包括脂蛋白将他们运送至全身各用。

The research team found a link between raised levels of a type of cholesterol called LDL, low density lipoprotein, and the development of disease.

该研究团队发现，种名为低密度脂蛋白（简称LDL）胆固醇水平升高与患痴呆症有关联。

They also look at whether that cholesterol is being shuttled by low-density lipoproteins or LDL, the so-called 'bad' cholesterol, and high density lipoproteins or HDL, the 'good' cholesterol.

他们观察是否胆固醇被低密度脂蛋白（LDL）运送，叫做“坏”胆固醇，和高密度脂蛋白HDL，就是“好”胆固醇。
