Fructosylvaline. A simple model of the N-terminal residue of human haemoglobin A1c.
The phenylhydrazone of N-[D-fructosyl-(1)]-L-valine (1-deoxy-L-valine-D-fructose) was synthesized. The hydrazone was shown to exist in open form in basic solution and in closed form in acidic solution. The findings have bearings upon the discussion of the reaction of human haemoglobin A1c with phenylhydrazine.
