There was an increase in the isovaleryl and 3-OH butyryl carnitine levels, whereas there was a decrease in the levels of acetyl, propionyl, and palmitoylcarnitine.
Proteins identified in these studies included albumin, ES1 carboxylesterase, propionyl and methylcrotonyl coenzyme A carboxylase-[alpha], and pyruvate carboxylase.
Propionyl CoA is converted to L-methylmalonyl CoA and the mutase (with vitamin B12 as coenzyme) converts this to succinyl CoA, which is part of the tricarboxylic acid (Krebs) cycle of metabolism.
To control the exotherm, the process as described suggests slow addition of propionyl chloride.
The process starts with the metabolism of various compounds in the mitochondrion to form propionyl CoA (Figure 1).
The parcel, which was mailed to a Tokyo medical company from China, contained three bottles filled with a type of propionyl chloride, which is used in the manufacture of medicines, police said.

Normally propionyl-CoA is metabolized to methylmalonyl-CoA by the action of propionyl-CoA carboxylase (PCC), but if the metabolite is in excess the propionyl species is released from the mitochondrion after conversion by carnitine palmitoyl transferase II to the corresponding acylcarnitine (Fig.
Testosterone and acetyl-L-carnitine with propionyl L-carnitine improved all outcomes of male aging and ED and were more powerful than Viagra alone or improved its effectiveness after radical prostate surgery.
The level of propionyl carnitine is highly increased in both diseases, arising from the transesterification of propionyl-CoA (Fig.
The hyperammonemia observed in methylmalonic acidemia is thought to arise because accumulated propionyl CoA interferes with formation of N-acetylglutamate, an obligatory activator of carbamyl phosphate synthase, the initial step in urea synthesis (4).
