The plaque eventually begins to occlude the blood vessel, causing ischemia and infarction in the heart, brain, or extremities. Eventually the fibrous cap may thin, and the plaque becomes unstable, … WebChylomicrons are assembled primarily in the intestine and contain a smaller version, apoB-48, whereas VLDL particles contain the larger apoB-100 surface protein and are primarily assembled in the liver. The functional role for VLDL and chylomicron particles is to deliver TG to peripheral tissue.
