What are macromolecules? |
They are structures of polymers made up of the molecular building blocks |
|
|
List 4 building blocks and the corresponding macromolecules they give rise to |
Amino acids - proteins Nuclei bases - nucleic acid (DNA & RNA) Simple carbohydrates- complex carbohydrates Lipids |
|
|
Give 4 examples of macromolecules |
Polysaccharides (complex carbohydrates) Nucleic acids Proteins Lipids |
|
|
Which macromolecules is different from the 4 and in what way? |
Lipids - because they are individual bulks of molecules that are not polymers and have varying shapes and sizes |
