Caption: Figure 4: Classic path of polyamine metabolism consists of the following: (1) arginine is converted to ornithine through the action of ARG (arginase) in the urea cycle; (2) putrescine is formed from the reaction of ornithine decarboxylation catalyzed by ODC1 (ornithine decarboxylase-1).
Since amines were mainly produced by amino acid decarboxylation, the lower contents of bioactive amines could be the result of a previous minor level of precursors.
Glutamate decarboxylase or glutamic acid decarboxylase (GAD) is an enzyme that catalyzes the decarboxylation of glutamate to GABA and C[O.
The resulting metabolic shift directs tyrosine metabolism towards the decarboxylation pathway with unphysiological production of noradrenalin, dopamine together with increased synthesis of amines such as tyramine, octopamine and synephine.
Orexins have been shown to be present in the cells of the gas-trointestinal mucosa that are involved in amine precursor uptake and decarboxylation (APUD), which are scattered throughout the exocrine epithelia.
This subsequently causes reduction of the oxidative decarboxylation of pyruvate resulting in decreased utilization of oxygen and glucose.
IQA biosynthesis is generally considered to begin with the conversion of tyrosine to both dopamine and 4-hydroxyphenylacetaldehyde via a sequential decarboxylation, ortho-hydroxylation and deamination pathway (Fig.
The O/C versus N/C atomic ratios indicate that the decarboxylation processes were in line with the reduction of the N concentration relative to the C content in HAs.
Glucose, taken up by secondary active transporter proteins, is degraded to pyruvate which is then introduced into the citric acid cycle after its decarboxylation to acetyl coenzyme A.
Suspected colonies were identified by using chemical tests including Gram staining, Indole, Methyl Red, Voges Proskauer, Citrate Utilization, Triple Sugar Iron, Lysine Decarboxylation (Agarwal et al.
They may derive from cells of the amine precursor uptake and decarboxylation system, which originate in neural crest and then migrate to different epithelial sites within the body.
Determining TVB-N allowed to quantify the low molecular weight volatile bases and amino compounds produced by the microbial decarboxylation of amino acids and nitrogenated compounds, which are widely used as indicators of shelf life and, more specifically, to measure stages of deterioration or loss of freshness.
