Abstract:
Gel filtration and dialysis studies on the state of zinc in boar seminal plasma and vesicular secretion strongly suggest that the zinc is partitioned between two or more ligands of which the most likely are proteins and citrate. This partition is very sensitive to changes in pH and buffer composition and an increasing proportion of the zinc is precipitated at pH values above 7. No firmly bound protein zinc complex was found which could account for the close correlation between the zinc and protein nitrogen contents previously observed for these fluids.
