Dehydration and Hydrolysis Reactions
Introduction
Carbon – Organic Chemistry
Polymerization
• Polymer- Large molecule made of many parts
• Monomer- Subunit or building block for Polymer
Breaking and Forming Polymers
• Dehydration Synthesis – “take water out”– Joining monomers to add
polymers by adding water
• Hydrolysis– “break using water”– Breaking polymers into
monomers by adding water
Dehydration Synthesis
Monosaccharides
Disaccharide
Polysaccharide
Dehydration Synthesis
Dehydration Synthesis• Small molecules are joined together to
form larger molecules• Energy is used• Water is released
H2O
Dehydration Synthesis• Small molecules are joined together to
form larger molecules• Energy is used• Water is released
Hydrolysis
Hydrolysis• Large molecules are broken apart to
produce smaller molecules• Energy is released• Water is used to split the bond
H2O
Hydrolysis• Large molecules are broken apart to
produce smaller molecules• Energy is released• Water is used to split the bond
Protein formation…Hydrolysis or Dehydration?
• Monomer– Amino Acid
• Polymer– Polypeptide
• Bond– Peptide
