Blog 4 Describe how the structure of macromolecules affect their function.

First a macromolecule a giant molecule formed by the joining of smaller molecules, usually by a condensation reaction. Some are polysaccharides, proteins, and nucleic acids. The shape of their structure is consistent with their diverse functions.For example if a protein's structure is slightly changed it can affect the protein;s ability to function. When an amino acid is substituted for a normal one at a position in the primary structure of hemoglobin the protein that carries the oxygen in red blood cells can cause sickle-cell disease. In this case the structure of a macromolecule can be crucial to their function.
