| IDENTIFICATION OF SOME MACROMOLECULES | | INTRODUCTION Dehydration-synthesis is a reaction that occurs to form different types of macromolecules. It is a reaction that leaves a macromolecule structure along the lines of developing its own specific function in a living organism. The 4 most common ones are carbohydrates which includes monosaccharides and polysaccharides, lipids, proteins and nucleic acids (Mack 2012). Scientists identify different types of macromolecules to achieve a better understanding on how they function in our bodies. This can be achieved by studying their chemical properties and structure.
