Effect of dietary protein on vitamin A levels in plasma and liver of hypervitaminotic-A rats.
Level of vitamin A increased in plasma and liver in hypervitaminotic A albino rats fed normal quantity of protein in diet. In low protein fed state vitamin A level in liver increased due to accumulation of vitamin A and lack of carrier protein with an associated decrease of plasma vitamin A. In high protein fed rats the level of vitamin A in plasma increased due to enhanced transport while in liver it decreased. The results indicate that for normal transport of vitamin A adequate plasma protein level is essential.
