ABSTRACT

The effect of the hormonally active vitamin D3 formulation on the activity of porcine leukocyte lipoxygenase was studied. The rate of enzyme inhibition was vitamin dose-dependent and increased if pH values raised, while the vitamin inhibitory effect was decreased as the content of linoleic acid used as a substrate was increased.
