what elements are macromolecules made up of
First of all there are many macro-molecules essential to life. The basic molecules include: Proteins, which are comprised of amino acids. Lipids, which are made of fatty acids. Polysaccharides made up of carbohydrates. DNA and RNA made up from nucleotides. Other macromolecules include vitamins, organic acids and molecules involved in redox reactions. Here are some of the functions of the above mentioned molecules: Proteins- responsible for structural molecules (i.e. part of cell walls, membranes) and enzymes (molecules that catalyze a desired reaction).
