Document Summary
Fatty acids diffuse into the nearby cells: fatty acids are either immediately used for energy (oxidized) or re-esterified into tag and stored, glycerol travels. The loss of tag causes the lipoproteins remaining in the bloodstream to become smaller and more dense. Chylomicron remnants and vldl remnants still contain some tag and cholesterol. Repacked into vldl and secreted into the bloodstream or. Vldl remnants continue to circulate and lose more tag, forming low density lipoproteins (ldl) Ldl serves as a source of cholesterol to cells in the body. Ldl binds to the receptor and enters cells through the endocytosis. Lysosomes break down the ldl and release free cholesterol. Ldl can be uptaken by the liver and the cholesterol repackaged into vldl. Keep your ldl low and your hdl high . Cardiovascular disease is the #1 killer of us adults. Heart can cause a heart attack (myocardial infarction) Injury to the lining of the arteries promotes inflammation.
