Lipoproteins are a set of molecules composed of lipids
bound to proteins. This is one of the forms in which cholesterol
is present in the blood
, a low density lipoprotein
, differs from IDL, of intermediate density, and HDL
, with high density. LDL cholesterol
is called bad cholesterol
or atherogenic cholesterol and is responsible for deposits on the walls of arteries
: this is atherosclerosis
, a major factor in cardiovascular diseases
such as myocardial infarction
. If too much LDL cholesterol is accumulated, dietary rules are essential to reduce the intake of animal fats (except fish) and focus on vegetable fats. In some cases, drugs
lowering blood levels of the bad cholesterol, called statins are used. In contrast, HDL- cholesterol, good cholesterol
, plays a protective role in preventing the arteries from forming deposits.
