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...
As a general rule,HDL is considered “good” cholesterol, while LDL is considered “bad.” This is because HDL carries cholesterol to your liver, where it can be removed from your bloodstream before it builds up in your arteries. LDL, on the other hand, takes cholesterol directly to your ...

(RCT). Low HDL cholesterol is an important risk factor for CAD. HDL helps remove cholesterol from arteries in the early stages of disease and from established atherosclerotic plaque. This is why having low HDL is a risk factor and also why raising HDL to as high a level as possible helps...
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”
LDL cholesterol: Causes, risk factors, and treatment 低密度脂蛋白(LDL)胆固醇构成了人体内的大部分胆固醇。当一个人有太多的LDL胆固醇时,它会在血管壁上堆积,形成斑块。 随着时间推移,LDL胆固醇可能会使血管收缩,增加患心脏病的风险,因此人们有时把它称为“坏胆固醇”...
故而低密度脂蛋白（LDL）中的胆固醇被称为“bad cholesterol”。相反，HDL携带的胆固醇往往被带回肝脏分解并逆向排出体外，这样能防止游离胆固醇在肝外组织沉积，限制动脉粥样硬化的发生和发展，起到抗动脉粥样硬化的功效，是冠心病的保护因素，所以高密度脂蛋白（HDL）中的胆固醇被称为“good cholesterol”。
HDL returns the excess cholesterol to your liver which removes it from your body, if after a few same information, your questions about cholesterol or any medication you’ve been prescribed to help manage your cholesterol, speak to your health care provider, it is important to take your medicat...
HDL is good cholesterol that has a positive effect on our cardiovascular system. On the other hand, LDL is a type of bad cholesterol that forms plaque in our arteries due to deposition. Therefore, this is the key difference between HDL and LDL cholesterol. Functionally, HDL levels are expecte...
