transamination

 [trans″am-ĭ-na´shun]
the reversible exchange of amino groups between different amino acids.

trans·am·i·na·tion

(trans'am-i-nā'shŭn),
The reaction between an amino acid and an α-keto acid through which the amino group is transferred from the former to the latter; in certain cases the reaction may be between an amino acid and an aldehyde (for example, glutamate with glutamate semialdehyde via ornithine transaminase).

transamination

/trans·am·i·na·tion/ (-am″ĭ-na´shun) the reversible exchange of amino groups between different amino acids.

transamination

(trăns-ăm′ə-nā′shən, trănz-)
n.
1. Transfer of an amino group from one chemical compound to another.
2. Transposition of an amino group within a chemical compound.

transamination1

[-am′inā′shən]
the reaction between an amino acid and an alpha-keto acid in which the enzyme transaminase induces transfer of the amino group to the alpha-ketoacid.

transamination

Chemistry
A biochemical reaction in which an amino group is transferred from an amino acid—which becomes an alpha-keto acid upon losing the amino group—to an alpha-keto acid—which becomes an amino acid once it gains the transferred amino group.

trans·am·i·na·tion

(tranz'am-i-nā'shŭn)
The reaction between an amino acid and an α-keto acid through which the amino group is transferred from the former to the latter.

transamination

The reaction in which the amino group of an amino acid is transferred to a ketoacid, converting it into an amino acid.

Fig. 300 Transamination . The transfer of an amino group to form a different amino acid.

transamination

the process by which amino groups are transferred from one AMINO ACID to form another, using a keto acid as an intermediary. The mechanism takes place in the liver, and is important in the breakdown of excess amino acids to form keto acids and in the formation of new amino acids (perhaps not available in the diet) from keto acids. An example is shown in Fig. 300. ESSENTIAL AMINO ACIDS cannot be produced by transamination.

trans·am·i·na·tion

(tranz'am-i-nā'shŭn)
The reaction between an amino acid and an α-keto acid through which the amino group is transferred from the former to the latter.

transamination (tranzam´inā´shən),

n the reaction between an α-ketoacid and an amino acid in which the amino group moves to the α-ketoacid, creating a new amino acid and a new ketoacid.

transamination

the reversible exchange of amino groups between different amino acids.
