The stoichiometry of photophosphorylation

Biochemical and Biophysical Research Communications, 1965
Abstract Using chloroplasts from three different plant species in the presence of four different buffer systems we found that the P 2e ratio was consistently above 1.0 if the pH was between 8.4 and 9.4. At pH 8.9 the ratio was usually above 1.25 and indeed no single determination of the ratio fell below 1.1 at this pH unless Tris-HCl was ...

Stoichiometry

2009
Stoichiometry is the study of the quantities of reactants and products involved in a chemical reaction. In addition to identifying the reactants and products in a chemical reaction, a balanced equation gives useful information that is helpful in calculations.

Stoichiometry of chromatin proteins

Biochemical and Biophysical Research Communications, 1974
Abstract The stoichiometry of rat liver chromatin proteins has been estimated by quantitative disc electrophoresis. There are about 1.3 × 10 8 histone and 2.4 × 10 7 nonhistone polypeptide molecules per haploid genome, an average of one such molecule for every 21 and 117 base pairs of DNA, respectively.

Stoichiometry of vulcanization with sulfur

Journal of Polymer Science, 1951
Abstract In the study of vulcanization with natural rubber and other polymers of relatively high chemical unsaturation, it has always been difficult to represent the vulcanization process molecularly because of the complexity of the sulfur-polymer reactions.

Ecological Stoichiometry for Parasitologists

Trends in Parasitology, 2018
Ecological stoichiometry (ES) is an ecological theory used to study the imbalances of chemical elements, ratios, and flux rates among organisms and the environment to better understand nutrient cycling, energy flow, and the role of organisms in ecosystems.
