How Does It Make Sense That All Composition Of The Cell Membrane Is Largely A Lipid

1.Why does it make sense that all composition of the cell membrane is largely a lipid?

The cystol and all parts of the cell are made up of very polar; water-soluble molecules, which are hydrophilic “water loving”. The environment outside the cell is also very polar and water-soluble. In order to have an appropriate barrier between the inside of the cell and the outside, The membrane of the cell needs to be made of highly non-polar, organic material like lipids. The reason is because non-polar, organic matter like lipids and carbohydrates are very hydrophobic which means they are “water hating”. An example would be like mixing oil and water, they will never mix, because oil is like a lipid and it hates water.

This makes things within the cell harder to cross the membrane to the outside of the cell. So when you think about it, the best way to stop the mixing of things inside and outside the cell is to put something like a wall or membrane made out of material that is nothing like what the inside and outside are made of. Lipids are also very rigid molecules that help keep the shape of the membrane.

So the harder it is for things to travel the better it is. So these way things that are supposed to stay inside the cell will stay inside the cell, and things that are supposed to stay outside, will stay outside.
