Glyconic acid

Kostromina, N. A., Complex compounds of cerium, neodim, and samarium with glyconic acid, J. Inorg. Chem. (Russ). 5, 95-101 (1960). [Pg.508]

The hydroxy a-amino acids l-serine and l-threonine, used as models for the 2-amino-2-deoxy glyconic acids, have been complexed with Ni(II) at 37 °C in aqueous solutions of 0.15M potassium nitrate. Values for the stability constants were obtained from iso-pH titration data which were collected by alternate, small, incremental additions of metal ion and potassium hydroxide being made such that the pH of the solution remained nearly constant. The data were consistent with the predominance of MLn species, along with additional protonated and hydrolyzed complexes. There was no evidence for the involvement of the hydroxyl group in chelation. By the same iterative computations the complexes formed between borate and mannitol have been analyzed, and the stability constants have been calculated. Complexes with mannitohborate stoichiometries of I.T, 1 2, 1 3, and 2 1 were proposed. [Pg.205]

Figure 4.2.2 Top Fischer projections of a few common glycitols and glyconic acids. Note the symmetrical structure of D-mannitol. Bottom Molecular structures of (a) linear D-mannitol, (b) bent D-glucitol, (c) D-glucaric acid, and (d) crystal structure of water-in-soluble D-galactaric acid. In the latter structure the intermolecular hydrogen band pattern is indicated. Figure 4.2.2 Top Fischer projections of a few common glycitols and glyconic acids.
