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.
Nascent VLDL particles are released into the bloodstream via a process that depends upon apolipoprotein B-100. In the blood stream, nascent VLDL particles bump with HDL particles; as a result, HDL particles donate apolipoprotein C-II and apolipoprotein E to the nascent VLDL particle. Once loaded with apolipoproteins C-II and E, the nascent VLDL ...
[2] [5] Remnant cholesterol is primarily chylomicron and VLDL, and each remnant particle contains about 40 times more cholesterol than LDL. [6] Remnant cholesterol corresponds to all cholesterol not found in high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C). It is calculated as total cholesterol minus HDL-C and LDL-C.

[6] ALP activity is significantly increased in the third trimester of pregnancy. [11] This is due to increased synthesis from the placenta as well as increased synthesis in the liver induced by large amounts of estrogens. [11] [12] [13] Levels in the third trimester can be as much as 2-fold greater than in non-pregnant women. [11]
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]
Phytosterols are widely recognized as having a proven LDL cholesterol lowering efficacy' [72] A 2018 review found a dose-response relationship for phytosterols, with intakes of 1.5 to 3 g/day lowering LDL-C by 7.5% to 12%, [73] but reviews as of 2017 had found no data indicating that the consumption of phytosterols may reduce the risk of CVD. [74]
[7] The National Lipid Association recommends that people with familial hypercholesterolemia restrict intakes of total fat to 25–35% of energy intake, saturated fat to less than 7% of energy intake, and cholesterol to less than 200 mg per day. [8] Changes in total fat intake in low-calorie diets do not appear to affect blood cholesterol. [64]
