Abstract
The review and discussion represent, in the author''s own words, "an endeavor to correlate some of the known but hitherto widely scattered facts concerning the physiological inter-relations of ascorbic acid and Ca in animals and plants and to point out suggestive similarities in their action in the 2 groups of organisms. The subject is discussed under the following topics: 1. Relation of Ca to the boundary structure of cells. 2. Ascorbic acid in relation to cytoplasm and cell surfaces, cell walls, and intercellular substances. 3. Some aspects of the chemical nature of the cell wall and intercellular substances. 4. Loss of ascorbic acid in metabolic . processes. 5. Similarity of some physiological effects of ascorbic acid and Ca.".
