• enzymesbuild some substances and break others down
• oxireductases catalyze electron transfer from one molecule to another.
• transferases


  catalyze the transfer of functional groups.
• hydrolase 


  the hydrolysis of a chemical bond in biomolecules. also, a chemical compound is broken down by reaction with water.
• lyases


  catalyzing addition and elimination reactions; joining specific molecules or groups by a double bond.
• ligases


  reaction of joining two large molecules by establishing a new chemical bond.
• isomerases


  changes with one molecule.
• (specific emyzmes): amylase


  helps you to digest carbohydrates; secreted by pancreas and salivary gland
• protease


  released by the pancreas, responsible for breaking down peptide bonds for proteins.
• lipases


  naturally occuring enzyme; found in stomach and pancreatic juice; also releases a bile salts in small intestine

  primarily found in nerves and muscles
