About Biological Macromolecules
Biological macromolecules are large molecules that are found in lifeforms. They are complex molecules with lots of complex functions, and they react with one another to produce all of the chemical reactions that happen in life. Life, and biology, is a very complicated set of chemical reactions, and the biological macromolecules play a key role in them.
Proteins are the functional machinery of living organisms, carrying out a huge number of functions that keep organisms alive.
Carbohydrates are a useful energy source for living organisms, composed on carbon, hydrogen and oxygen.
Lipids are a large molecules which are not water soluble, and have important functions in cell structures, for insulation, and as a stable long term energy source.
Nucleic acids and other nucleotides are molecules that are used as an information storage medium, to store the instructions for creating an organism, as well as being involved in many other biological processes.
