Wikipedia

  1. Transamination

    Transamination is a chemical reaction that transfers an amino group to a ketoacid to form new amino acids. This pathway is responsible for the deamination of most amino acids. This is one of the major degradation pathways which convert essential amino acids to non-essential amino acids (amino acids that can be synthesized de novo by the organism). Transamination in biochemistry is accomplished by enzymes called transaminases or aminotransferases. α-ketoglutarate acts as the predominant amino-group acceptor and produces glutamate as the new amino acid. Aminoacid + α-ketoglutarate ↔ α-keto acid + glutamateGlutamate's amino group, in turn, is transferred to oxaloacetate in a second transamination reaction yielding aspartate. Glutamate + oxaloacetate ↔ α-ketoglutarate + aspartate

  1. transamination

    Transamination is a biochemical process in which an amino group from one amino acid is transferred to a carbon compound to form a new amino acid. This process, which is facilitated by enzymes known as transaminases or aminotransferases, plays a crucial role in nitrogen metabolism in cells.

  1. Transamination

    Transamination is a chemical reaction between two molecules. One is an amino acid, which contains an amine group. The other is a keto acid, which contains a keto group. In transamination, the NH2 group on one molecule is exchanged with the =O group on the other molecule. The amino acid becomes a keto acid, and the keto acid becomes an amino acid. Transamination in biochemistry is accomplished by enzymes called transaminases or aminotransferases. This process is an important step in the synthesis of some non-essential amino acids. The chirality of an amino acid is determined during transamination. This reaction uses the coenzyme PLP, and has been shown to be a kinetically perfect reaction. The product of transamination reactions depend on the availability of alpha-keto acids. The products usually are either alanine, aspartate or glutamate, since their corresponding alpha-keto acids are produced through metabolism of fuels. Lysine and threonine are the only two amino acids that do not always undergo transamination and rather use serine or threonine dehydrogenase. The second type of transamination reaction, which can be described as a nucleophilic substitution of one amine or amide anion on an amine or ammonium salt. For example, the attack of a primary amine by a primary amide anion can be used to prepare secondary amines:−−++
