When a red blood cell is placed in water, the water molecules will enter the cell rapidly as a result of osmosis. Osmosis is the process by which molecules moves through a cell permeable membrane from the region of lower concentration to that of higher concentration.
The inside of the red blood cell is more concentrated than the water in which it is placed, so water will move into the cell via osmosis.
This will make the cell to swell up and to burst open.<span />
High-density lipoproteins (HDL) refer to macromolecular complexes made up of lipids and that have the function of transporting dietary lipids to the liver.
<h3>What are lipoproteins?</h3>
They are macromolecules whose function is to package insoluble lipids in the aqueous medium of plasma and transport them from the intestine and liver to peripheral tissues and, from these, return cholesterol to the liver for elimination from the body.
<h3>Characteristics of High Density Lipoproteins (HDL)</h3>
- They are synthesized and secreted by the liver and to a lesser extent by the intestine.
- They transport cholesterol from peripheral tissues to the liver, this is known as “Reverse Cholesterol Transport”.
Therefore, we can conclude that lipoproteins are macromolecules whose function is to transport lipid molecules from one organ to another in the aqueous medium of plasma.
