Sources of propionate in inborn errors of propionate metabolism

Metabolism, 1990
Amino acids are widely regarded as the most important sources of propionate in disorders of propionate metabolism. Propionate production was measured in the fasting state by continuous infusion of sodium [1-13C]propionate in three children with methylmalonic acidemia (MMA) and three with propionic acidemia (PA).

Survey of baked goods for propionic acid and propionates

Food Additives and Contaminants, 1996
One hundred and thirty samples comprising bread (64), hamburger buns (33), pittas (16), cakes (9) and Christmas puddings (8) from various retail outlets in the UK, have been analysed for the preservative propionic acid. Only one sample of bread, two samples of hamburger buns and three samples of pitta contained propionic acid in excess of 1000 mg/kg ...

Measurement of propionate turnover in vivo using sodium [2H5]propionate and sodium [13C]propionate

Clinica Chimica Acta, 1989
The outcome for children with inherited disorders of propionate metabolism is poor. To facilitate development of improved treatment in these conditions, we described techniques for the estimation of the rate of production and removal of propionate in vivo.

The pathway of propionate oxidation

Biochimica et Biophysica Acta, 1953
Abstract 1. 1. The oxidation of labelled propionate in the presence of large pools of unlabelled l -lactate, d -lactate and pyruvate gives rise to the appearance of label in these pools. The appearance of label suggests that the compounds mentioned are in equilibrium with the actual intermediates.

Cardiomyopathy in propionic acidaemia

European Journal of Pediatrics, 1993
Following the death of a patient with propionic acidaemia with a cardiomyopathy we reviewed 19 patients with the same disorder for evidence of cardiomyopathy. Six patients were found to meet the diagnostic criteria. Three patients died and in the other three the cardiac disease resolved completely.

Methylmalonic and propionic aciduria

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, 2006
AbstractMethylmalonic and propionic aciduria (PA) are the most frequent forms of branched‐chain organic acidurias. These autosomal recessive disorders result from deficient activity of methylmalonyl‐CoA mutase and propionyl‐CoA carboxylase, respectively.
