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]
Even people with very low LDL levels achieved by statin treatment are exposed to increased risk if their HDL levels are not high enough. [19] [non-primary source needed] Very high HDL-C levels (≥80 mg/dL in men, ≥100 mg/dL in women) appears to be detrimental to cardiovascular outcomes.
The desirable LDL level is considered to be less than 100 mg/dL (2.6 mmol/L). [97] [98] Reference ranges for blood tests, showing usual, as well as optimal, levels of HDL, LDL, and total cholesterol in mass and molar concentrations, is found in orange color at right, that is, among the blood constituents with the highest concentration.
Knowing one's levels, he says, would be a signal to be more aggressive about keeping LDL cholesterol and blood pressure down, and just being aware enough to live a heart-healthy life.
Structure of a chylomicron (the largest lipoprotein). ApoA , ApoB , ApoC , ApoE are apolipoproteins ; green particles are phospholipids ; T is triglyceride ; C is cholesterol ester . A lipoprotein is a biochemical assembly whose primary function is to transport hydrophobic lipid (also known as fat ) molecules in water, as in blood plasma or ...
A lipid profile or lipid panel is a panel of blood tests used to find abnormalities in blood lipid ( such as cholesterol and triglycerides) concentrations. [not verified in body] The results of this test can identify certain genetic diseases and can determine approximate risks for cardiovascular disease, certain forms of pancreatitis, and other diseases.
The elevated triglyceride levels (>5 mmol/L) are generally due to an increase in very low density lipoprotein (VLDL), a class of lipoprotein prone to cause atherosclerosis. [ 33 ] Both conditions are treated with fibrate drugs, which act on the peroxisome proliferator-activated receptors (PPARs), specifically PPARα, to decrease free fatty acid ...
