Disorders of fructose metabolism (Homo sapiens)
From WikiPathways
Description
Fructose is converted into fructose-1-phosphate, this reaction is facilitated by fructokinase (also called ketohexokinase)(encoded by KHK). Connected to this reaction is the metabolic disease "essential fructosuria" which causes a deficiency in fructokinase. After this fructose-1-phosphate is converted into glyceraldehyde and dihydroxyacetone-phosphate, this is facilitated by aldolase B (encoded by ALDOB). connected to this reaction is the metabolic disease "hereditary fructose intolerance", which is the result of the absence of aldolase B. The glyceraldehyde produced from this reaction will be converted into D-glycerate through the activity of Aldehyde dehydrogenase 1 family, member A1 or ALDH1A1 (encoded by the ALDH1A1 gene). The D-glycerate will be converted (according to the book) into 2-Phosphoglyceric acid through the activity of Glycerate kinase (encoded by GLYCTK)
