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.

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.

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

(2004), this reduction highlights the better exploitation of the energy available in feed caused by the effect of the additive on gram positive bacteria, with suppression of caloric losses, mainly caused by the reduction of gas production, reduction of amino acid deamination and increased propionate production.
Reaction cocktail in 0.1 M Tris-HCl buffer (pH 8.0) contained the 4 NTPs (0.6 mM each), Ca[Cl.sub.2] (3.5 mM), 5 units of RNase inhibitor, 5 units of DNase 1, and 5 [micro]g actinomycin D for both the amination, and the deamination directions.
It is also involved in the deamination or removal of amino acids.
Fluvoxamine is extensively metabolized in the liver, primarily through oxidative demethylation and deamination. (1) Nine metabolites constitute 85% of the urinary excretion product; the main metabolite is fluvoxamine acid.
(21) As there was no recorded change in amino acid metabolism, this effect may be explained by reduced AMP deamination.
