Phospholipids provide cell protection and act as a barrier to certain molecules. They decide which molecules can enter or exit the cell. What sterols do Sterols are also part of plant and animal cell membranes. In human membranes, the most important sterol is cholesterol. You can also find ste...
Lipids are fats. In the body they take the form of phospholipids, cholesterol and fatty acids. Although fats play a role in obesity and disease, your body needs a certain amount of fat to function -- also known as essential body fat. Men need at least 3 percent body fat and women need...

Liposomes are microscopic vesicles developed in a laboratory environment. Each liposome has an outer wall comprised of lipids similar and sometimes identical to those which compose the cell wall, allowing liposomes to interact directly with cells. There are a number of applications for liposomes, rangi...
