Answer:
LDL
Explanation:
LDL comes from low density lipoprotein. It represents the most dangerous form of cholesterol.
What it does is it loads cholesterol particles from the liver and elsewhere into the arteries. That is, if you walk in excess in the circulation, it causes an accumulation in the vessels that can, over time, clog them or form thrombi. This is the trigger for heart attack and stroke. Ideal LDL rates vary from person to person. Those most at risk of having a heart attack should aim for especially low levels of this molecule.
HDL, in turn, comes from high density lipoprotein. And this molecule has an action contrary to that of LDL. Like a janitor, HDL removes cholesterol from the arteries and takes them back to the liver, preventing their accumulation. Hence why it is desirable to keep it high.
Nowadays, people are asked to target a rate above 40 mg / dl. It turns out that studies with drugs that raise these rates have not shown great benefits for the heart. Thus, what is recommended today is to increase the concentration of HDL mainly with physical activity.
