The effect of iron on metabolism of vitamin C in chickens.
The objective of the paper was to show the effect of supplementation of iron on vitamin C synthesis in chickens. Iron administered per as caused than increase of vitamin C synthesis in chickens. The increase of vitamin C synthesis following iron supplementation is due to the alteration of L-gulono-gamma-oxidase activity in tissues; the enzyme taking part in last phase of vitamin C formation, and due to increase of D-glucuronic acid level, an intermediate product during vitamin C synthesis. High doses of iron cause the increase of vitamin C metabolism in chickens.
