Cholesterol

Cholesterol "bad" and "good"

Cholesterol is a fatty substance that is produced mainly in the liver, and also comes with our food inside the body, it is necessary for the formation of cell membranes and hormones.

Cholesterol cannot dissolve in the blood, so it moves in the bloodstream with the help of proteins. As a result of the addition of cholesterol to the carrier protein, two types of complexes are formed, conventionally - bad and good. Bad cholesterol delivers cholesterol to body cells. Cells absorb the necessary amount of cholesterol, and the excess remains in the blood with all the consequences that follow.
