Transport and Storage of 14 G-Riboflavin in the Retina and Liver of Rats. ∗

Abstract

Summary

Deficient rats retain slightly less of an injected amount of ¹⁴C-riboflavin per unit weight of liver than do controls, but levels in retina were similar for the two groups. A possible small preferential decrease in flavoproteins of liver, but not of retina, is suggested. No significant difference in rate of uptake by the tissues of the two groups was found. Riboflavin in the retinas of albino rats exists predominantly as FAD and FMN with free riboflavin levels comparable to those found in liver.
