A new coordination complexes of cobalt (II) and copper (II) with Pyrrolyl-2-carboxaldehyde isonicotinylhydrazone have been synthesized and characterized by elemental analysis, conductance measurements, magnetic susceptibility measurements, 1H NMR spectroscopy, IR spectroscopy, UV-Vis-absorption spectroscopy, ESR spectroscopy and thermal analysis. IR spectra suggest ligand acts as a dibasic donor coordinating through the azomethine nitrogen atom and enolic oxygen atom. ESR and ligand field spectra suggest a tetrahedral geometry for Co(II) complex and a square planar geometry for Cu(II) complexes.

These pathways involve something unusual, either the structure of the amino acid is different enough than the other common amino acids, or sulfur is involved in their synthesis. In any case, unique enzymes are involved in every step of the way. Here we just examine what they start with and how much it costs the cell.

Trytophan synthesis is complex and involves 5 steps from chorismate. Glutamate donates an amine group in the first step of the pathway and pyruvate is lost from chorismate. In the next threes steps a ribose sugar is added, this eventually contributes to the 5 membered ring of tryptophan. Energy is contributed to the process in the form of hydrolysis of pyrophosphate. This hydrolysis helps drive the addition of the ribose sugar in the second step of the reaction. In the last step of the pathway serine serves as the donor of the carbon amino group of tryptophan.
