Lipid Metabolism Library
Lipid metabolism disorders (including inborn errors of lipid metabolism) are illnesses where trouble occurs in breaking down or synthesizing fats (or fat-like substances). Lipid metabolism disorders are associated with an increase in the concentrations of plasma lipids in the blood such as LDL cholesterol, VLDL, and triglycerides which most commonly lead to cardiovascular diseases.
