Chylomicron structure ApoA, ApoB, ApoC, ApoE (apolipoproteins); T (triacylglycerol); C (cholesterol); green (phospholipids). Chylomicrons transport lipids absorbed from the intestine to adipose, cardiac, and skeletal muscle tissue, where their triglyceride components are hydrolyzed by the activity of the lipoprotein lipase, allowing the released free fatty acids to be absorbed by the tissues.
Remnant cholesterol is the cholesterol content of triglyceride-rich lipoproteins, which consist of very low-density lipoproteins and intermediate-density lipoproteins with chylomicron remnants. [2] [5] Remnant cholesterol is primarily chylomicron and VLDL, and each remnant particle contains about 40 times more cholesterol than LDL. [6]

Its measurement is commonly used to detect risk of ...
Very-low-density lipoprotein (VLDL), density relative to extracellular water, is a type of lipoprotein made by the liver. [1] VLDL is one of the five major groups of lipoproteins (chylomicrons, VLDL, intermediate-density lipoprotein, low-density lipoprotein, high-density lipoprotein) that enable fats and cholesterol to move within the water-based solution of the bloodstream.
High levels of lipoprotein(a) are a significant risk factor for atherosclerotic cardiovascular diseases via mechanisms associated with inflammation and thrombosis. [16] The links of mechanisms between different lipoprotein isoforms and risk for cardiovascular diseases, lipoprotein synthesis, regulation, and metabolism, and related risks for ...
Women with the highest levels of LDL cholesterol had a 36% higher risk for heart disease compared with those with the lowest levels. The highest levels of Lp(a) indicated a 33% elevated risk, and ...
Hyperlipidemia is abnormally high levels of any or all lipids (e.g. fats, triglycerides, cholesterol, phospholipids) or lipoproteins in the blood. [2] The term hyperlipidemia refers to the laboratory finding itself and is also used as an umbrella term covering any of various acquired or genetic disorders that result in that finding. [3]
Chylomicron retention disease is a disorder of fat absorption. [1] It is associated with SAR1B. [2] Mutations in SAR1B prevent the release of chylomicrons in the circulation which leads to nutritional and developmental problems. [3]
