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
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...
