The Behavior of Isocitric Acid in Excised Leaves of Bryophyllum Calycinum During Culture in Alternating Light and Darkness.

The behavior of the organic acids and starch of Bryophyllum leaves during culture in continuous light.

When leaves of’ Bryophyllum calycinum are picked at daybreak and cultured in water in darkness, certain changes in composition occur that are not observed in such leaves when they are exposed to the normal diurnal alternation of light and darkness. In effect the leaves are exposed t’o a night period of abnormal length and the stresses that are thus set up give rise to reactions the ultimate phy...

The Metabolism of the Organic Acids of Tobacco Leaves * XVIII. EFFECT OF CULTURE OF EXCISED LEAVES IN SOLUTIONS OF POTASSIUM L,-ISOCITRATE HUBERT

Among the unsolved problems of the biochemistry of organic acids in green leaf tissue is the position of isocitric acid in the metabolic system. This acid accumulates in substantial amounts in the leaves of plants of the botanical family Crassulaceae, and has been found in moderate amounts in a number of other species, notably the fruit of the blackberry (Rubus fructicosus), where it was first ...

The preparation of optically active isocitric acid from Bryophyllum leaf tissue.

d-Isocitric acid’ has, in recent years, attracted much interest as one of the organic acids concerned in reactions catalyzed by the enzymes of various animal and plant tissues. A demand has accordingly arisen for specimens of this rare substance for use in investigations of the enzyme systems involved. The fortunate observation that d-isocitric acid is present in the leaves of succulent plants ...
