  1. Reaction 1
    • -D-galactose converted to D-galactose 1-phosphate 
    • -galactokinase(enzyme)
    • -irreversible reaction
    • -ATP required
  2. Reaction 2
    • -start with D-galactose 1-phosphate and UDP glucose(uradine diphosphate covalently bonded to glucose)
    • -irreversible reaction
    • -uridylyltransferase is enzyme, transfers UDP to galactose sugar and phosphate from galactose to glucose 
  3. Reaction 3
    • -starts with UDP-D-galactose
    • -uses enzyme 4-epimerase 
    • -reversible reaction
    • -product is UDP-D-glucose 
  4. Reaction 4
    • -starts with UDP-D-glucose and inorganic pyrophosphate 
    • -uses enzyme UDP-glucose pyrophosphorylase 
    • -products are UTP (uradil triphosphate) and D-glucose 1-phosphate
    • -reversible reaction
  5. Reaction 5
    • -starts with D-glucose 1-phosphate
    • -enzyme phosphoglucomutase 
    • -reversible reaction 
    • -product is glucose 6-phosphate
