In vivo the reaction proceeds in the opposite direction. It is available in three strengths: 20 mg/mL; 40 mg/mL; 80 mg/mL. Failure to convert methylmalonyl-CoA into succcinyl-CoA in the mitochondrial matrix results in methylmalonic acidemia, an autosomal recessive group of inborn errors of protein metabolism in which methylmalonic acid concentrations in blood and urine are elevated without a concomitant elevation in homocysteine. Synonyms: DEPO-MEDROL. Later, in the duodenum, it is liberated by trypsin where it binds to the intrinsic factor produced by the parietal cells of the stomach. The latter may be characterized by recurrent episodes of ketoacidosis, hyperammonemia, leukopenia, thrombocytopenia, and anemia, which can result in multiple organ failure and even death.262 The enzymatic defect is treated with protein restriction, cobalamin supplementation, and metronidazole to suppress microbial propionate production. Instead, as first demonstrated in the housefly (Dillwith et al., 1982), insects metabolize propionate to 3-hydroxypropionate and then to acetyl-CoA, with carbons 3 and 2 of propionate becoming carbons 1 and 2 of acetyl-CoA (Fig. 2). It has been suggested that the neurological signs of vitamin B12 deficiency may result, at least in part, from the production of these abnormal fatty acids in neural tissues. 2-, A flavoprotein (FAD) from Ascaris suum. Survivors typically have severe residual neurologic impairments, including dystonia.260 MRI studies show alterations in myelination and changes in the basal ganglia.261 Pathologically, there is necrosis of the putamen or globus pallidus.
