1. Hydrolysis and Dehydration Synthesis

2. Dehydration Synthesis
“Dehydration” – loss of water “Synthesis” – to make
Water is removed and monomers are covalently bonded.
2 molecules are covalently bonded to each other by a loss of a water molecule
Each monomer contributes part of the lost water molecule
One monomer gives a hydroxyl group (-OH)
The other one a hydrogen (-H)

6. Hydrolysis: Hydro “water”; lysis “split”
Opposite reaction of dehydration synthesis.
Polymers are broken down to monomers by hydrolysis
Break with water
By adding water, the bonds between the monomers break; a hydrogen attaches to one monomer and a hydroxyl attaches to the other
