[Study on the LMCT band of zinc-bovine serum albumin].
The structure of metal centre in 1:1 zinc-bovine serum albumin complexes have been studied with UV spectrum. The data from literature is used to calculate the optical electronegativity of three pi orbits of histidyl imidazole. Using these data, we infer that two charge transition bands of complex of zinc ions and bovine serum albumin come from transition of pi 2, pi 3 electrons of histidyl imidazole to zinc ions.
