Low-density lipoprotein (LDL) is one of the five major groups of lipoprotein that transport all fat molecules around the body in extracellular water. [1] These groups, from least dense to most dense, are chylomicrons (aka ULDL by the overall density naming convention), very low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL ...
A special kind of protein, called apolipoprotein, is embedded in the outer shell, both stabilising the complex and giving it a functional identity that determines its role. Plasma lipoprotein particles are commonly divided into five main classes, based on size, lipid composition, and apolipoprotein content: HDL, LDL, IDL, VLDL and chylomicrons.
A protein specific to chylomicrons is ApoB48. There is an inverse relationship in the density and size of lipoprotein particles: fats have a lower density than water or smaller protein molecules, and the larger particles have a higher ratio of internal fat molecules with respect to the outer emulsifying protein molecules in the shell. ULDLs, if ...
Very-low-density lipoprotein size is variable, with diameters ranging from approximately 35 to 70 nm. [4] Some researchers further classify VLDL particles into VLDL1 and VLDL2 based on size (as measured by Svedberg flotation units), where VLDL1 particles are larger and contain more triglycerides, while other researchers create a tripartite system by subdividing VLDL1 into larger VLDL1 and ...
In humans, excess cholesterol in the blood is captured by low-density lipoprotein (LDL) and removed by the liver via endocytosis of the LDL receptor. [4] Recent evidence indicates that the members of the LDL receptor gene family are active in the cell signalling pathways between specialized cells in many, if not all, multicellular organisms. [5 ...
[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.

LDLR pathway Schematic representation of the LDL receptor protein. The LDL receptor gene is located on the short arm of chromosome 19 (19p13.1-13.3). [9] It comprises 18 exons and spans 45 kb, and the protein gene product contains 839 amino acids in mature form. A single abnormal copy (heterozygote) of FH causes cardiovascular disease by the ...
