deamination

 [de-am″ĭ-na´shun]
removal of the amino group, -NH2, from a compound.

de·am·i·na·tion

, deaminization (dē-am'i-nā'shŭn, dē-am'i-ni-zā'shŭn),
Removal, usually by hydrolysis, of the NH2 group from an amino compound.

deamination

/de·am·i·na·tion/ (de-am″ĭ-na´shun) removal of the amino group, —NH2, from a compound.

deamination

[dē′aminā′shən]
the removal, usually by hydrolysis, of the NH2 radical from an amino compound. Also called deaminization.

de·am·i·na·tion

, deaminization (dē'am-i-nā'shŭn, dē-am'i-nī-zā'shŭn)
Removal, usually by hydrolysis, of the NH2 group from an amino compound.

deamination

Removal of the amino group from a molecule. When an NH2 group is replaced by an oxygen atom a ketone is formed and the process is described as oxidative deamination. If the amino group is terminal, the process should, strictly, be called deamidation.

deamination

the removal of the amino group (NH2) from a molecule, as in the release of ammonia (NH3) from AMINO ACIDS, the residue of which can then enter the KREBS CYCLE usually via ACETYLCOENZYME A. The amino group then enters the ORNITHINE CYCLE.

de·am·i·na·tion

, deaminization (dē'am-i-nā'shŭn, dē-am'i-nī-zā'shŭn)
Removal, usually by hydrolysis, of the NH2 group from an amino compound.

deamination (dēam´inā´shun),

n a chemical alteration of α-amino acids that removes ammonia (NH3) from glutamate.

deamination

The demonstration that phenolic compounds hampered the detection of hydrogen peroxide when added directly to the fluorometric assay, while not pargyline or semicarbazide, brought further evidence that it was not the generation of hydrogen peroxide occurring during catalyzed oxidative deamination that was prevented by the phenolic compounds but rather the interaction of the MAO-generated or SSAO-generated hydrogen peroxide with chromogenic mixture.

However, PEA is subjected to a rapid deamination by peripheral monoamine oxidase B (MAO-B) which, like monoamine oxidase A (MAO-A), catalyzes the degradation of neuroactive and vasoactive amines in the central nervous system and in peripheral tissues.
Suspected colonies (maximum five) were randomly selected from each plate and confirmed by biochemical tests, including fermentation of glucose, lactose and sucrose, hydrogen sulfide production, urease activity, phenylalanine deamination, lysine decarboxylation, citrate, methyl red and indole tests.
13] It is based on the enzymatic deamination of adenosine to inosine, with the release of ammonia which is determined by Berthelot's reaction.
DNA damage by nitrosation, deamination and oxidation.
Techniques based on DNA modification by sodium bisulfite are unable to distinguish between methylation and hydroxymethylation, since both 5-mC and 5-hmC do not undergo deamination after reacting with sodium bisulfite, and 5-mC and 5-hmC contents are mixed up in the final results.
An increase in global DNA methylation might be associated with an increased spontaneous mutation rate: Methylated cytosines are more prone to deamination than unmethylated cytosines, which increases the likelihood of C [right arrow] T transitions (Ehrlich et al.
