Lipids classification structure and function biology discussion
Answers
Lipids are another group of important biological molecules present in all cellular organisms and some viruses. Unlike the other groups of biological molecules, lipids are highly heterogenous in chemical structure. But all of them possess a common physical property which is that they are all non-polar compounds, insoluble in water and soluble in organic solvents like ether, chloroform etc.
Lipids form a major component of all types of biological membranes. The cytoplasmic membrane which is the limiting layer separating the biological cell from the outer environment is present universally in all organisms. It consists mainly of a lipoprotein bilayer. In eukaryotic cells various compartments or cell organelles are also separated by membrane system constituting the cytoskeleton.
