CHOLESTEROL LDL HDL

CHOLESTEROL LDL HDL

Cholesterol can,t dissolve in the blood. it has to be transported to and from the cells by carries called lipoproteins.Low Density Lipoprotein,or LDL, is Known as "Bad" Cholesterol. High- density Lipoprotein or HDL, IS KNOWN AS "GOOD" Cholesterol.

LDL/LOW DENSITY LIPOPROTEIN:-
When too much LDL(BAD) cholesterol circulates in blood, it can slowly build up in the inner wals of the arteries that feed the heart and brain, if a clot forms and blocks a narrowed artery, heat attack or stroke can result.
HDL/HIGH DENSITY LIPOPROTEIN:-
About 1/4 th to 1/3 cholesterol carried by HDL. HDL cholesterol is known as GOOD cholesterol,because high levels of HDL seem to protect against heat attack.Low levels of HDL <40 mg/dl also increase to risk of heart disease.
