The Proteins of Green Leaves
Previous work (1) has shown that about 50 per cent of the total protein nitrogen contained in a tobacco leaf which had recently completed growth by expansion is associated with particulate structures of leaf protoplasm such as nuclei, chloroplasts, etc. The other 50 per cent of the protein nitrogen remains soluble in the presence of neutral buffers. In the analytical ultracentrifuge, the solubl...
متن کاملThe proteins of green leaves. IV. A high molecular weight protein comprising a large part of the cytoplasmic proteins.
Previous work has shown that the soluble cytoplasmic proteins comprise about 30 per cent of the total protein contained in spinach and tobacco leaves (1, 2). Thus, on a dry weight basis, the cytoplasmic proteins constitute in the neighborhood of 10 per cent of the total dry matter of the leaf, including cellulose. In an attempt to resolve the soluble proteins present in leaf cytoplasm, resort w...
متن کاملGreen synthesis of Silver nanoparticles using the aqueous extract of Prangos ferulaceae leaves
Nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. In this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of Prangos ferulaceae leaves. The synthesized silver nanoparticles were characterized by UV-Vis spectroscopy, sc...

متن کاملThe Non-volatile Organic Acids of Green Tobacco Leaves*
Accurate information on the organic acids of leaves is surprisingly meager; even the identity of the acidic substances in many of the plant tissues that have been investigated is still in doubt. Franzen and Keyssner (1) pointed out some years ago that the identity of the malic acid had been conclusively proved in only 15 of 235 plants reported in the literature to contain this substance and a s...
