Secretion of HDL from the liver into the circulatory system regulates the release of HL into the body's bloodstream. This is because factors that increase the release of HDL (such as fasting, leading to low levels of HDL) increases the amount of HL bound to HDL and released into the bloodstream.
The secretion of high-density lipoprotein (HDL) from the liver into the circulatory system controls the release of cholesterol (Chol) into the body's bloodstream. This is because factors that increase the release of HDL, such as fasting, lead to an increase in the amount of Chol bound to HDL and released into the bloodstream.
