Additional Enzymatic Reaction

common enzymes that accelerate or catalyze biochemical reactions

• Protease (proteinase) - catalyzed the breakdown of proteins

  • Essential anytime we eat

• Catalase - accelerated the decomposition of hydrogen peroxide (H2O2) into water and oxygen

• Lipase - catalyzed the breakdown of lipids (fats)

6 major categories of enzymes

• Hydrolases - catalyze hydrolysis

  • Hydrolysis - the cleavage or breaking apart of chemical bonds by the addition of water

• Isomerases - promote intermolecular rearrangements by altering bonds and/or confirmations within the same molecule producing a different molecule having the same molecular formula (isomer)

• Ligands - cause covalent bonds to be formed between molecules

• Lyases - cause the cleavage (break) of bonds by means other than hydrolysis or oxidation

• Oxidoreductases - catalyze the transfer of electrons from the reluctant to the oxidant

• Transferases - act to transfer a specific functional group from one molecule to another
