Where are lipids made in the cell?

About 50% of the total membrane surface in an animal cell is provided by endoplasmic reticulum (ER). The organelle called 'endoplasmic reticulum' occurs in both plants and animals and is a very important manufacturing site for lipids (fats) and many proteins. read more

Lipids serve three main purposes. Energy storage; Cell Signaling; Formation of Membranes; Nearly every form of membrane within the cell (and around the cell itself) is composed of primarily lipids, in addition to certain proteins (for transportation, binding, or structural support). As a fun aside here is a gif of the motor protein Kinesin moving molecules. read more

Using this approach, lipids may be divided into eight categories: fatty acids, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids, and polyketides (derived from condensation of ketoacyl subunits); and sterol lipids and prenol lipids (derived from condensation of isoprene subunits). read more

The membrane that surrounds a cell is made up of proteins and lipids. Depending on the membrane’s location and role in the body, lipids can make up anywhere from 20 to 80 percent of the membrane, with the remainder being proteins. read more
