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)...

Atherosclerosis is caused not by native circulating LDL particles but rather by oxidized LDL particles in the arterial wall. Oxidized LDL particles unlike native particles are taken up by macrophages via scavenger receptors...
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...

The cholesterol in the form of LDL is so-called “bad cholesterol”, and the cholesterol in the form of HDL is so-called “good cholesterol”. Why? (5分) 相关知识点: 试题来源: 解析 LDL将胆固醇带到血管壁堆积形成斑块,导致动脉硬化,被称为“坏胆固醇”;HDL将多余胆固醇运回肝脏分解,减少血管...
LDL Cholesterol Low-density lipoprotein, or “bad” cholesterol, makes up the majority of the cholesterol in your body. Heart disease and stroke risk increase if LDL cholesterol levels are high. LDL cholesterol can build up on the walls of your blood vessels when your body has too much of ...
