Lipids consist of of increase to 3 fatty mountain coupled in addition to a molecule the glycerol. These fatty mountain can generally be any fatty acid in any kind of combination.

Lipids room molecules of various chemical structures, therefore they can not be gift in a basic formula/ structure block prefer e.g. Carbohydrates, proteins...Some that their usual properties are: insolubility in water and an excellent solubility in necessary solvents such as chloroform, ether and also benzene.More info below


Some lipids have three major biological roles:storing energy, building biological membranes, and also transmitting signals in between cells

Their chemical structure is very different and also so as their attributes in nature.As a big group lipids include :

triacylglycerols (fat, oils)
*
R 1, R 2 and also R 3 are hydrocarbon groups of lengthy chain fat acids, in a greater number of carbon atoms. The higher the ratio of unsaturated fatty acids in your composition the much more are they fluid (oils).

phospholipids

Phospholipids are the membrane materials of each cell.
*

steroidsThey are created from 4 carbon rings, come which different functional teams are attached. They are found in all live cells. The key steroid is cholesterol, comprise 27- C atoms.

*
On this picture of cholesterol you can see 4 rings and different functional groups that are attached come the ring. Cholesterol is the significant molecule in the synthetic of hormones, regulatory and also signaling molecules.
