Biochemistry Dehydration and Hydrolysis Reactions

Introduction All living things made of elements C, H, O, NP, SOthers

Carbon – Organic Chemistry Forms 4 covalent bonds Energy is stored in covalent bonds Carbon can form large stable chains or rings or chains of rings

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

Small molecules are joined together to form larger molecules Energy is used Water is released H2OH2O

Dehydration Synthesis Small molecules are joined together to form larger molecules Energy is used Water is released

Hydrolysis

Large molecules are broken apart to produce smaller molecules Energy is released Water is used to split the bond H 2 O

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
