How is the metabolism of fructose related to the fructose 1-phosphate pathway?

Fatemeh said: (Jun 10, 2015)  
Fructose is converted into fructose 1 phosphate via the enzyme fructokinase which can then be used in glycolysis by getting converted into glycerlaldehyde 3 phosphate and dihydroxyacetone phosphate via the enzyme Aldose B.

Hope it helps!

How about fructose 6 phosphate?

Bernard Kakala said: (Dec 22, 2015)  
Fructose 6 phodphate is phosphorylated into fructose 1, 6 diphosphate then enzymically broken down into dihydroxyacetone and glyceladehyde phosphate.

Good explanations. Thank you all.

Since glucose can be converted to fructose (1, 6) and these can further be converted to dihydroxyacetone and glyceraldehyde phosphate so it takes both pathways.

During glycolysis, fructose converted into fructose 1, 6 bisphosphate than metabolized into glyceraldehyde 3 phosphate.
