Mad. Diez et al., COORDINATION OF MERCURY(II) TO CARBOHYDRATE ALPHA-AMINO-ACIDS DERIVEDFROM GLUCOSE AND MANNOSE, Journal of inorganic biochemistry, 54(2), 1994, pp. 141-145
The complex formation of mercury(II) with carbohydrate alpha-amino aci
ds derived from glucose and mannose was investigated at 25 degrees C i
n 0.1 mol dm(-3) NaClO4, aqueous solution by glass-electrode potentiom
etry. From the analysis of the emf data in the systems by use of compu
ter programs MINIQUAD and SUPERQUAD, it was concluded that the species
formed in all systems are [ML(2)] and [ML(OH)]. The formation constan
ts in the systems measured from different salts of mercury(II) show th
at the values obtained from HgCl2 are extremely less than those observ
ed from Hg(NO3)(2), probably because chloride is bound to mercury(II)
with high stability.
