LDL中的胆固醇容易在血管壁沉积形成斑块导致动脉硬化,HDL中的胆固醇帮助清除血管壁多余胆固醇并运回肝脏代谢。 1. LDL功能分析:LDL负责将胆固醇从肝脏运输到外周组织。当血液中LDL浓度过高时,多余的胆固醇会被氧化并渗入血管内皮,引发泡沫细胞形成和动脉粥样硬化斑块。2. HDL的逆向运输机制:HDL可将外周组织(包括血管壁)...
HDL 携带的胆固醇主要是使之回到肝脏中去,从而得以得到代谢并排除,最后可以达到一个减少胆固醇沉积的作用,提供动脉血管的HDL,血浆胆固醇量其实是减少的。 所以说低密度脂蛋白(LDL)中的胆固醇是“bad cholesterol” ,而高密度脂蛋白(HDL)中的胆固醇是“good cholesterol”。反馈...

over time and elevate the risk of heart disease, people sometimes refer to it as “bad cholesterol.” HDL cholesterol, onthe other hand, takes cholesterol to the liver for removal, rather than allowing it to accumulate in the blood vessels. As a res...
3.为什么说低密度脂蛋白(LDL)中的胆固醇是“ bad cholesterol”,而高密度脂蛋白HDL)中的胆固醇是“ good cholesterol”
Cholesterol: Bad vs. Good LDLstands forlow-density lipoprotein. Like all fats, cholesterol can't dissolve in blood, which is mostly water, so it attaches itself to a protein. 'Lipo' means fat, thus 'lipoprotein'. The protein acts like a bus, traveling around the body via the bloodstream...
High-density lipoprotein cholesterol (HDL-C) is often termed the “good” cholesterol while LDL-C is usually termed the “bad” cholesterol. HDL and LDL are two of five major lipoproteins that enable transport of different fat molecules, including cholesterol. The other lipoproteins are chylomicron...
Is HDL Good or bad? HDL (high-density lipoprotein), or“good” cholesterol, absorbs cholesterol and carries it back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke. ...
