<prompt> The first step in fructose metabolism in the liver isIsomerization of glucosePhosphorylation to fructose 1, 6 bisphosphate by ATPPhosphorylation to fructose 6 phosphate by ATPPhosphorylation to fructose 1 phosphate by ATP  <response>: Fructose metabolism The first step isFructose ATP to ADP FructokinaseFructose-1-Phosphate Second step: Fructose-1-Phosphate can conve into Glyceraldehyde or DHAP with the help of Aldolase Fructose-1-Phosphate aldolaseGlyceraldehyde conveed to Glyceraldehyde-3-Phosphate with the help of Triose kinase and ATP conveed to ADPDHAP conveed to Glyceraldehyde-3-Phosphate with help of Triose-phosphate isomerase.
