Hereditary fructose intolerance is an autosomal recessive congenital disorder caused by mutation in the gene encoding the synthesis of the type B aldolase enzyme, located on chromosome 9q31.1. This mutation reduces the enzymatic activity of type B aldolase, expressed mainly in the liver, but which can also be found in intestinal and renal cells. The role of aldolase is to cleave phosphorylated fructose (fructose-1-phosphate) into glyceraldehyde and dihydroxyacetone phosphate. Thus the body’s ability to metabolize fructose is dramatically affected, resulting in the accumulation of fructose in liver cells in the form of fructose-1-phosphate.

The Right Accumulation

The accumulation of fructose-1-phosphate in the hepatocyte cytoplasm leads to the sequential sequestration of inorganic phosphate and the activation of adenosine monophosphate (AMP) deaminase which irreversibly catalyzes the deamination of AMP to IMP (inosine monophosphate) and adenine is converted to uric acid. Nicotinamide Mononucleotide or NMN is from the nucleotides family. The nucleotides are those organic modules that are found in maximum food items that we consume. Along with the other nucleotides The NMN happens to be made of 3 parts. In simpler words, the higher the NMN is, the higher is the level of NAD+. Choosing the right nmn powder manufacturer is important in this case.

The Right Ratio

Consequently, the ratio between AMP and adenosine triphosphate (ATP) changes dramatically, the tissue depletion of ATP being a consequence of the massive degradation of uric acid and the impossibility of regenerating ATP reserves (the process of oxidative phosphorylation in mitochondria – cell power plants- cannot occur in the absence of inorganic phosphate, which is sequestered in the cytoplasm). Low availability of ATP in liver tissue affects gluconeogenesis (causing hypoglycemia and vomiting) and protein synthesis (causing a reduction in the production of clotting factors and other proteins vital to the body).

  • The inability of fructose to be cleaved into glyceraldehyde and dihydroxyacetonphosphate, which participates in the processes of glycolysis and gluconeogenesis, disrupts the homeostasis of carbohydrate metabolism. This explains the hypoglycemia and metabolic acidosis that accompany hereditary fructose intolerance. Intense degradation of uric acid Explain could clinically impaired hyperuricemic. Also, the competition between urate and lactate for renal excretion is considered responsible for the occurrence oflactic acidosis.
  • Another consequence of increased fructose-1-phosphate concentrations is the inhibition of fructokinase by a feedback mechanism, causing an increase in the level of free fructose in the blood (fructose).
  • Intracellular accumulation of fructose-1-phosphate may induce hepatocellular toxicity , which may be one of the mechanisms responsible for severe liver dysfunction / destruction. The onset of proximal renal tubulopathy is not a well-defined cause, but it can often be complicated by amino acids, glucosuria, phosphaturia, and bicarbonate.


The prevalence of hereditary fructose intolerance is unknown, but some studies in the United States and Europe estimate its frequency in 1 in 20,000 newborns, respectively 12,000 – 58,000 births according to an analysis conducted. For fighting against different diseases, the use of the NAD+ form happens to be of the best importance. Just like the NMN powder, the NR powder is also quite effective. In the elevation of the NAD+ levels, that faces decline as the age increases, both of these powers are used for a number of physical ailments. But other than that the NR powder and the NMN powder is also available now that work as perfect supplement options. You can choose the best nr powder manufacturer for the same.
