METABOLISM OF ASCORBIC ACID IN DEVELOPING CHICK EMBRYOS AND ITS SIGNIFICANCE

概要

A histochemical investigation on the content of ascorbic acid in chick embryos of 30 hours to 12 day age group was undertaken using an improved histochemical technique. High deposition of ascorbic acid in tissues like the developing brain, optic vesicle, gut, liver, kidney and feather germ suggests that actively growing embryonic tissues are rich in this vitamin and possess its faster turnover. The localization of ascorbic acid in the mesenchymal areas may be related to the synthesis of collagen. Our findings support the view of some others that ascorbic acid and its free radical are important sources of electron energy for biosynthetic processes in growing tissues.
