A Zn2+ binding constituent of fababeans.
Binding of Zn2+ by an aqueous extract of fababeans was estimated spectrophotometrically. Treatment of the extract with phytase removed virtually all of the phytate and about 82% of the Zn2+ binding. Gel permeation chromatography of the extract showed that the Zn2+ binding factor eluted at the same volume as phytate. The major Zn2+ binding constituent of the bean extract appears to be phytate.
