摘要：

The VO2+-Vitamin-B-6 (HVB6) complexes with the amino acids: glycine (Hgly), alpha-alanine (H alpha ala), beta-alanine (H beta ala), proline (Hpro), serine (Hser), threonine (Hthr), methionine (Hmet), phenylalanine (Hphe), leucine (Hleu), isoleucine (Hile), valine (Hval) and tryptophan (Htrp) were studied and the binary and tertiary stability constants determined. The potentiometric measurements were gathered using 1.0 mol.dm(-3) NaCl at 25 degrees C as ionic medium. Experimental data were analyzed using the computational program, LETAGROP, and HYSS was used to obtain the respective distribution diagrams. [GRAPHICS] .
