3. Carbohydrates, Lipids and Proteins

3.1

• Describe How Chemical groupings determine the structures of macromolecules.
  • Groups of atoms called functional groups occur in biological molecules.
  • Each functional group has specific chemical properties and when it attaches to a larger molecule it confers the properties onto the larger molecules.

• Describe How The structures of macromolecules reflect their functions

  • The four kinds of biological macromolecules are present in roughly the same proportions in all living organisms.
  • Each biological macromolecule performs one or more functions.
  • The sequence and chemical properties of the chain of monomers in a macromolecule determine its 3-D shape and function

3.2

• How Do Monomers of proteins link together to make the macromolecule

  • Each amino acid has both a carboxyl function group and an amino functional group attached to the same…
