Macromolecules/Monomers/Polymers

What is a macromolecule?

Complex molecules with a relatively large molecular mass

Give three examples of macromolecules

Proteins

Lipids

Some carbohydrates

What are monomers?

Small, basic molecular units

Give two examples of monomers

Monosaccharides

Amino acids

What are polymers?

Large complex molecules

What are polymers made up of?

Long chains of monomers joined together

Give two examples of polymers

Proteins

Most carbohydrates

What reaction makes polymers?

Condensation

Describe what happens in a condensation reaction to make a polymer

Chemical bond forms between monomers, releasing a molecule of water

What reaction breaks polymers?

Hydrolysis

Describe what happens in a hydrolysis reaction to make a polymer

Chemical bond between monomers is broken, using a molecule of water
