Cholesterol metabolism : Cholesterol is readily oxidized to form Oxysterols. HDL metabolism is complex, but one role of HDL is to obtain cholesterol from peripheral tissues and other lipoproteins and transport it to where it is needed most—other cells, other lipoproteins (using cholesteryl ester transfer protein [CETP]), and the liver (for clearance). Bundles called lipoproteins carry cholesterol throughout the body. CHOLESTEROL PRESENTED BY:-SILENT KILLERS 2. But cholesterol is necessary for the creation of hormones, vitamin D, and enzymes needed for digestion. Metabolic disease - Metabolic disease - Disorders of lipid metabolism: Lipids are large, water-insoluble molecules that have a variety of biological functions, including storing energy and serving as components of cellular membranes and lipoproteins. At normal levels, it is an essential substance for the body. Cholesterol transport and pathways, drugs used for treatment of atherosclerosis.
