Step 1
Low-density lipoproteins (LDL)
Answer
Low-density lipoproteins (LDL) are a type of lipoprotein in which cholesterol is bound to proteins in the bloodstream. They are commonly known as 'bad' cholesterol because they can lead to health issues. LDL is considered harmful as it is believed to accumulate in the arteries, causing plaque formation. This buildup can damage blood vessels and is associated with an increased risk of heart disease.
Step 2
High-density lipoproteins (HDL)
Answer
High-density lipoproteins (HDL) are often referred to as 'good' cholesterol. They play a crucial role in the body by helping to remove cholesterol from the bloodstream. HDL particles assist in transporting cholesterol back to the liver, where it can be processed and eliminated. This process reduces the risk of heart disease and counteracts the harmful effects of cholesterol buildup in the arteries.
