Lipoproteins
Lipoproteins are complexes of lipids and proteins that transport fats through the bloodstream. They vary in density and composition, influencing their function and role in health. The main types include chylomicrons, VLDL, LDL, and HDL, each serving distinct purposes in lipid metabolism and cardiovascular health.

LDL (Low-Density Lipoprotein)
LDL, or Low-Density Lipoprotein, is often referred to as 'bad cholesterol' because high levels can lead to plaque buildup in arteries, increasing the risk of cardiovascular diseases. It carries cholesterol from the liver to the cells, but when present in excess, it can contribute to atherosclerosis and other vascular issues.

Cholesterol and Cardiovascular Risk
Cholesterol is a waxy substance essential for various bodily functions, but its levels must be balanced. High levels of LDL cholesterol are associated with an increased risk of heart disease and stroke, while HDL (High-Density Lipoprotein) is considered 'good cholesterol' as it helps remove excess cholesterol from the bloodstream, thus reducing cardiovascular risk.
