What is the difference between macromolecule and polymer?

Charles Zellstines  Follow

Macromolecules are molecules made of smaller subunits. Polymers are macromolecules made of repeating subunits.

For example, a protein is both a macromolecule and a polymer since it is made of repeating units of amino acids. Theorically, there are no limits to how many amino acids there can be in a protein molecule. A tryglyceride is a macromolecule but not a polymer. Tryglycerides are made of a glycerol binded with three fatty acids. There are no repeating units. So tryclycerides are not polymers.
