Book excerpt: Excerpt from The Carbohydrate Economy of Cacti The best evidence gained since the time of Sachs points to the conclusion that sugars are the first products which accumulate in the process of the photosynthesis of carbon compounds in the chlorophyllous cell. Thus, sugars may be considered the starting-point for the synthesis of the tre mendons number of substances found in living things, both vegetable and animal. What the sugar or mixture of sugars is which thus commands the center of attention in the metabolism of plants and of almost all living things is still a question of much dispute and uncertainty; nor does the solution of this problem seem possible until we have gained more knowledge of the transformations which the various sugars undergo in the cell, inde pendent Of photosynthesis. It has long been known that in the leaf, under circumstances, the polysaccharides are converted into the simpler sugars and vice versa, by what appears to be the shifting of an equilibrium by means of enzyme action. It is self-evident that a knowledge of these trans formations must be obtained before the problem of the first sugar syn thesized can be attacked. Not only in relation to the question of the immediate products of photo synthesis is the study of the carbohydrate equilibrium important, but also to the question of metabolism. In a very large number of plants, especially the higher ones, both the living and the lifeless matter consists in the main of material of carbohydrate nature. The lifeless matter forms the walls, vessels, supporting frame-work, and often a considerable amount of the reserve food-material. Those portions of the plant in which the manifesta tions of life appear, as for instance the chromatin of the nucleus and the protoplasm itself, contain a considerable quantity of carbohydrates, the life less being formed from the living and the living drawing upon the lifeless for support. It is, however, a question whether the difference between the living and lifeless is essentially one of chemical constitution. The idea that the living substance or protoplasm is a complex compound of more or less definite chemical constitution no longer seems tenable. Protoplasm, a mixture of so many different substances, undoubtedly varies in composition in different organisms. It is in all probability the study of the physical and chemical properties of protoplasm as a colloidal mixture (such proper ties as imbibition of water, electrical charges, and surface phenomena) which will yield the most illuminating results.

Available in PDF, EPUB and Kindle. Book excerpt: The acid metabolism of certain succulent plants, now known as Crassulacean Acid Metabolism (CAM) has fascinated plant physiologists and biochemists for the last one and a half centuries. However, since the basic discoveries of De Saussure in 1804 that stem joints of Opuntia were able to remove CO from the 2 atmosphere during the night, and of Heyne in 1815 (see Wolf, 1960) that organic acids accumulate in the leaves of Bryophyllum calycinum during the night, the two main aspects of CAM, diurnal CO gas exchange and metabolism of malic acid, 2 have first been studied nearly independently. Hence, it is not surprising that most research to elucidate the mechanism of CAM has been during the last 15 years since CO exchange and malate metabolism were studied and interpreted in its 2 context. These efforts finally resulted in a clear realization that the CAM phenom enon is a variation on the mode of how plants can photosynthetically harvest CO from the atmosphere. 2 The interpretation of CAM in this sense was stimulated by the discovery of another variant of photosynthesis, the C -pathway (see Black, 1973; Hatch and 4 Slack, 1970; Hatch, 1976). Because this newly discovered photosynthetic pathway is recognized to be very closely related to the CAM pathway, the work on the latter became intensified during these last years.
