===Structure===
Each native LDL particle enables emulsification, i.e. surrounding the fatty acids being carried, enabling these fats to move around the body within the water outside cells. Each particle contains a single [[apolipoprotein]] B-100 molecule ([[Apolipoprotein B|Apo B-100]], a protein that has 4536 [[amino acid]] residues and a mass of 514 [[Atomic mass unit|kDa]]), along with 80 to 100 additional ancillary proteins. Each LDL has a highly hydrophobic core consisting of [[Polyunsaturated fat|polyunsaturated fatty acid]] known as [[Linoleic acid|linoleate]] and hundreds to thousands (about 1500 commonly cited as an average) of [[ester]]ified and unesterified cholesterol molecules. This core also carries varying numbers of triglycerides and other fats and is surrounded by a shell of phospholipids and unesterified cholesterol, as well as the single copy of Apo B-100. LDL particles are approximately 22 nm (0.00000087 in.) to 27.5 nm in diameter and have a mass of about 3 million daltons. Since LDL particles contain a variable and changing number of fatty acid molecules, there is a distribution of LDL particle mass and size. Determining the structure of LDL has been a tough task because of its heterogeneous structure. However, the structure of LDL at human body temperature in native condition, with a resolution of about 16 [[Angstroms]] using [[cryogenic electron microscopy]], has been described in 2011.
