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
