(Eating raw cannabis material that has not been heated to decarboxylate the acidic form of THC will produce only a minimal effect.) The slow action of orally ingested THC is due to its being transported from the stomach to the liver where it is converted to 11-hydroxy-THC, a more potent and longer lasting cannabinoid than THC.
(vi) Progressive degradation by OH attacking dimethylphenyl-amino groups, aldehydes which decarboxylates into C[O.sub.2].
Malic enzyme decarboxylates malate into pyruvate with mitochondria operating alternative pathways for the metabolism of glycolysis-derived phosphoenolpyruvate (PEP) and providing metabolic flexibility to plants (TAIZ; ZIEGER, 2004).
Klebsiella pneumoniae is a nonmotile enteric organism that ferments lactose, decarboxylates lysine, hydrolyzes urea, and forms large mucoid colonies, due to the presence of capsule (Koneman 2008).
[10-13], OH radical makes the main contribution to degradation of methylene blue and its intermediates, where the first steps use six hydroxil radicals, and produce an alcohol, then an aldehyde which is spontaneously oxidized into acid, and decarboxylates into CO2 by photo-Kolbe reaction.
Heating anacardic acids converts them to the alcohols (cardanols), but does not destroy their activity (Himejima and Kubo 1991) unless high heat is used, which decarboxylates them (Patel and Patel 1936).
Jonathan Ott (1976) has found that ibotenic acid decarboxylates to muscimol when exposed to acidic conditions, and suggested that ibotenic acid may be converted to muscimol in the acidic environment of the stomach.
This has been reported (22) to involve an initial reaction with water to form an unstable carbamic acid intermediate that spontaneously decarboxylates into an amine and carbon dioxide, as shown in Figures 4A-C.
The reduced ferredoxin is produced within the hydrogenosome by pyruvate:ferredoxin oxidoreductase (PFOR), which decarboxylates pyruvate to acetyl-CoA and [CO.sub.2] (Lindmark and Muller, 1973; Muller, 1993; Payne et al., 1993; Hrdy and Muller, 1995a; Homer et al., 1999).
