fructose 1-phosphate aldolase
Quick Summary
Fructose-1-phosphate aldolase is an enzyme crucial for carbohydrate metabolism, specifically in the breakdown of fructose. It catalyzes the reversible cleavage of fructose-1-phosphate into two smaller, three-carbon sugars: dihydroxyacetone phosphate and glyceraldehyde 3-phosphate. This reaction is a key step in glycolysis, the process by which cells break down glucose for energy.12
A deficiency in fructose-1-phosphate aldolase leads to hereditary fructose intolerance (HFI). In individuals with HFI, ingesting fructose or sucrose causes a buildup of fructose-1-phosphate, leading to symptoms such as vomiting, hypoglycemia, liver dysfunction, and kidney problems. Dietary restriction of fructose and sucrose is the primary treatment for HFI.3

Symptoms of HFI appear after the ingestion of fructose and thus present later in life than do those of galactosemia. Fructose is present in fruits, table sugar (sucrose), and infant formulas containing sucrose. Symptoms may include failure to gain weight satisfactorily, vomiting, hypoglycemia,…
