HDL is called good cholesterol because -
a) Removes cholesterol from extrahepatic tissues
b) Causes transport of cholesterol to extrahepatic tissues
c) Stimulate hepatic TGs synthesis
d) Activates lipoprotein lipase

Correct Answer - A
Ans. is ‘a’ i.e., Removes cholesterol from extrahepatic tissues
The HDL particles are referred to as scavengers because their
primary role is to remove free (unesterified) cholesterol from
extrahepatic tissues, which is then excreted through bile. This is a
crucial mechanism that prevents the inappropriate accumulation of
cholesterol in peripheral tissues. Because accumulation of
cholesterol in tissues is strongly associated with the development of
atherosclerosis, the level of HDL in serum is inversely related to the
incidence of MI (myocardial infarction). Thus, HDL is
cardioprotective and anti-atherogenic in nature, and is referred to as
“good cholesterol”.
Therefore, HDL-Cholesterol appears to be the best independent
predictor of coronary artery disease (inverse relationship) than any
other known risk factor. That means low HDL is a much stronger
predictor of coronary artery disease than increased LDL cholesterol
or increased total cholesterol.
