Fructose Unit Converter
Fructose is a simple sugar (monosaccharide) commonly found in fruits, honey, and high-fructose corn syrup. It is metabolized primarily in the liver, where it is quickly shunted into glycolysis and gluconeogenesis pathways.
Fructose levels are not measured routinely but may be assessed to diagnose Hereditary Fructose Intolerance (HFI), a severe autosomal recessive disorder caused by a deficiency in the enzyme aldolase B. Ingestion of fructose by HFI patients leads to the toxic accumulation of fructose-1-phosphate, resulting in hypoglycemia, metabolic acidosis, and liver failure. This converter facilitates accurate switching between the SI molar unit (mmol/L) and the conventional mass unit (mg/dL).

Clinical Context
Reference Range: In healthy individuals, serum fructose levels should be very low, often < 0.5 mg/dL. The test is primarily qualitative, seeking the presence of fructose metabolites.
For toxicological or genetic purposes, Ethylene Glycol and Methanol have similar presentations (high anion gap metabolic acidosis). However, fructose poisoning is treated by strict dietary restriction, not antidotes like Fomepizole. The conversion factor relies on MW 180.16 g/mol: 1 mmol/L ≈ 18.016 mg/dL.

Frequently Asked Questions & Tips
Yes. Fructose and Glucose share the same chemical formula (C6H12O6) and therefore share the same molecular weight and conversion factor.
Unlike glucose, fructose metabolism bypasses key regulatory steps, leading to rapid accumulation of toxic intermediates in HFI if the enzyme aldolase B is deficient.
