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.

1)United States for 2000 was determined from estimates of water withdrawals for the eight categories of public supply, domestic, irrigation, livestock, aquaculture, industrial, mining, and thermoelectric power.<span> total surface-water withdrawals were 323,000 Mgal/d, or 79 percent of the total withdrawals for all categories of use. About 81 percent of surface water withdrawn was freshwater. Total ground-water withdrawals were 84,500 Mgal/d, of which 99 percent was freshwater. Nearly all (98 percent) saline-water withdrawals were from surface water.
2)</span>Large amounts of water are stored in the ground. The water is still moving, possibly very slowly, and it is still part of the water cycle. Most of the water in the ground comes from precipitation that infiltrates downward from the land surface. <span>he term groundwater is used to describe this area. Another term for groundwater is "aquifer," although this term is usually used to describe water-bearing formations capable of yielding enough water to supply peoples' uses. Aquifers are a huge storehouse of Earth's water and people all over the world depend on groundwater in their daily lives.
