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.
[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. [7]
LDL particles are approximately 22 nm (0.00000087 in.) to 27.5 nm in diameter and have a mass of about 3 million daltons. [7] Since LDL particles contain a variable and changing number of fatty acid molecules, there is a distribution of LDL particle mass and size. [4]
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 ...
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]
The full-length human VLDLR genome is located on locus 9p24 on chromosome 9. It consists of a 40 kb segment that includes 19 exon-coding sequences, which is one more exon than encoded by LDLR.
With a size ranging from 5 to 17 nm, HDL is the smallest of the lipoprotein particles. [2] It is the densest because it contains the highest proportion of protein to lipids . [ 2 ] Its most abundant apolipoproteins are apo A-I and apo A-II .
Viva La Dirt League (VLDL) are a New Zealand group of professional sketch comedy YouTubers. [2] The founding members are Rowan Bettjeman, Alan Morrison and Adam King, but their productions have featured other regular cast members such as Byron Coll, Hamish Parkinson, David Correos, Britt Scott Clark, [3] Ben Van Lier, [4] Ellie Harwood, [5] Phoenix Cross, Rhiannon McCall, Rory Nolan and Robert ...
