I google translated El's last post, just thought I'd save others the trouble:

"Zinc and vitamin A interact in several ways. Zinc is a component of retinol-binding protein, a protein necessary to transport vitamin A in the blood. Zinc is also necessary for the enzyme that converts retinol (vitamin A) into retina. This latter form of vitamin A is necessary for the synthesis of rhodopsin, a protein in the eye that absorbs light and is therefore involved in dark adaptation. Zinc deficiency has been associated with decreased release of vitamin A from the liver, which may contribute to the night blindness symptoms seen with zinc deficiency (31, 32)."
