Hint: The primary function of lipoprotein is to transport hydrophobic lipid (also known as fat) molecules in water, such as blood plasma or other extracellular fluids. They are made up of a Triglyceride and Cholesterol center encased in a phospholipid outer shell, with the hydrophilic portions facing outward and the lipophilic portions facing inward.
Complete answer:
The outer shell contains apolipoprotein, a type of protein that both stabilizes the complex and gives it a functional identity that determines its function. Lipoproteins include enzymes, transporters, structural proteins, antigens, adhesins, and toxins. Plasma lipoprotein particles are an example (HDL, LDL, IDL, VLDL, and chylomicrons). These plasma particles are divided into subgroups.
Chylomicrons and microns (meaning small particles) are lipoprotein particles made up of triglycerides (85–92%), phospholipids (6–12%), cholesterol (1–3%), and proteins (1–2%). They are also known as ultra low-density lipoproteins (ULDL). They are responsible for transporting dietary lipids from the intestines to other parts of the body.
ULDLs are one of five major types of lipoproteins (sorted by density) that allow fats and cholesterol to move around in the bloodstream's water-based solution. ApoB48 is a chylomicron-specific protein.
Lipoprotein particles have an inverse relationship between density and size: fats have a lower density than water or smaller protein molecules, and larger particles have a higher ratio of internal fat molecules to outer emulsifying protein molecules in the shell.
Thus, Triglycerides, phospholipids, cholesterol, and proteins make up chylomicrons, which are lipoprotein particles. These are small droplets found in the intestine after fats have been digested. They are responsible for transporting dietary lipids from the intestines to other parts of the body. The activity of lipase hydrolyzes triglyceride components at various sites, releasing free fatty acids.
Note:
Chylomicrons transport lipids from the intestine to adipose, cardiac, and skeletal muscle tissue, where their triglyceride components are hydrolyzed by lipoprotein lipase activity, allowing the released free fatty acids to be absorbed. Chylomicron remnants are formed when a large portion of the triglyceride core is hydrolyzed and taken up by the liver.
