Low plasma adiponectin levels have been shown in humans to be correlated with hypertriglyceridemia and low HDL cholesterol, independent of the degree of intraabdominal fat and insulin resistance (18, 19). Once the chylomicrons (or other lipoproteins) travel through the tissues, these particles will be broken down by lipoprotein lipase in the luminal surface of endothelial cells in capillaries to release triglycerides. Metabolism is the process your body uses to make energy from the food you eat. Metabolism is the chemical process your body uses to transform the food you eat into the fuel that keeps you alive.
