Abstract
ESTIMATIONS of the ascorbic acid (vitamin C) content of the crystalline lens, by the indophenol titration method of Tilman, indicate that the crystalline lens contains about 0.26–0.46 milligrams ascorbic acid per gram of lens. Von Euler and Martius1, Birch and Dann2, and Müller3 are of opinion that a considerable amount of the iodine-reducing substances in the crystalline lens, hitherto considered to be glutathione, is actually ascorbic acid.
