Another is high density lipoprotein — or HDL cholesterol, which is the " good" cholesterol.

另一种是高密度脂蛋白——或者高密度脂蛋白胆固，这是一种有益的胆固。

The other one is high-density lipoprotein, or HDL.

另一个是高密度脂蛋白，或称 HDL。

You've probably heard of some of these. One is low density lipoprotein — also known as LDL cholesterol.

你可能听说过其中的一些。一种是密度脂蛋白——也被称为密度脂蛋白胆固。

Right. One is your level of low-density lipoprotein cholesterol, or LDL.

对。一个是你的密度脂蛋白胆固，或 LDL。

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

饱和脂肪会产生密度脂蛋白，即 LDL ，这是一种有害的胆固。

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

在这些细胞中，胰岛素激活脂蛋白脂肪酶，一种帮助脂肪细胞堆积更多脂肪分子的酶。

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

但他们不能理解固是怎么进到血液里的，包括脂蛋白将他们运送至全身各处的作用。

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，这种名为密度脂蛋白（简称LDL）的胆固的升高与患痴呆症有关联。

The answer is lipoproteins, four specialized proteins made by the liver that surround fats and allow them to move in the bloodstream as an emulsion.

答案是脂蛋白，这是肝脏制造的四种特殊蛋白质，它们包围着脂肪，使它们能够以乳液的形式在血液中移动。

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.

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

Like, there was this really cool study on silencing that E. coli outer membrane lipoprotein gene, you know, the one called LPP.

比如， 有一项非常酷的研究是关于沉默大肠杆菌外膜脂蛋白基因的，你知道的， 那个叫做 LPP 的基因。

It's carried around the body in our blood by different types of lipoprotein and that's important because it's responsible for the terms good and bad cholesterol.

它由不同类型的脂蛋白携带在我们的血液中，这很重要，因为它负责好胆固和坏胆固。

Metabolic syndrome exists when you have at least three risk factors, including excess stomach fat contributing to an enlarged waist size, high triglycerides, high blood pressure, high fasting blood sugar or a low high-density lipoprotein level.

当你的身体传递至少有三个危险信号时，就存在代谢综征，包括导致腰围增大的过多胃脂肪、高甘油三酯、高血压、高空腹血糖或高密度脂蛋白。

But an excess of low-density lipoprotein, or LDL, the so-called " bad" cholesterol, in the blood can build up to form a fatty plaque on the inside of your arteries, permanently increasing the resistance, and hindering blood flow.

但是血液中过量的密度脂蛋白，即所谓的“坏”胆固，会在动脉内部形成脂肪斑块，永久增加阻力，阻碍血液流动。
