What is a lipoprotein? A cluster of lipids and protein molecules used to transport lipids in blood and lymph An organic compound of three carbons that serves as the backbone for triglycerides A triglyceride with three saturated fatty acids associated with protein used to hold hydrogen atoms A molecule of glycerol with two fatty acids and phosphorus that is water soluble and serves as an emulsifier

It is composed of a core of hydrophobic lipids (such as cholesterol and triglycerides) surrounded by a shell of hydrophilic proteins (such as apolipoproteins). Show more…

The four lipoproteins that transport lipids throughout the body are globular structures composed of a lipid center surrounded by a coat of protein. Each lipoprotein has a different density, determined by the ratio of protein to lipid; the more protein each lipoprotein contains, the higher its density. The density determines how the lipoprotein functions. Match the below mention lipoproteins with the given Lipids. a. This lipoprotein contains the most cholesterol of all lipoprotein and about 25% protein. b. This lipoprotein contains a mixture of lipids, most of which is 60% triglycerides and about 10% protein. c. This lipoprotein contains the most triglycerides and the least protein. d. This lipoprotein contains 50% of its composition as protein and other 50% is composed of triglycerides, cholesterol and phospholipids. Lipids: 1. Chylomicron 2. VLDL 3. LDL 4. HDL 5. Micelle

Lipoprotein are relatively large, spherical clumps of protein and lipid molecules that circulate in blood of mammals. They are like suitcases that move cholesterols, fatty acids remnants, triglycerides and phospholipids from one place to another in the body. Given what you know about the insolubility of lipids in water, which of the four kinds of lipids would you predict to be on the outside of a lipoprotein clump, bathed in the fluid portion of blood? Protein shapes often are clues to their functions. The human leukocyte antigen (HLA) is an example of a recognition protein on the surface of vertebrate body cells. Some immune system cells use HLA to distinguish self (the body’s cells) from nonself. Each HLA has a jawlike region that can bind bits of an invader or some other threat and sound the alarm. Relate the misfold of jawlike region to what may happen to the function of HLA.
