1,3-Bisphosphoglyceric acid (1,3-Bisphosphoglycerate or 1,3BPG) is a 3-carbon organic molecule present in most, if not all, living organisms.It primarily exists as a metabolic intermediate in both glycolysis during respiration and the Calvin cycle during photosynthesis. 1,3BPG is a transitional stage between glycerate 3-phosphate and glyceraldehyde 3-phosphate during the fixation/reduction of ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
The composition of this layer can be complex, but one constituent is probably basic zinc carbonate, Zn 5 (OH) 6 CO 3. [8] The reaction of zinc with water is slowed by this passive layer. When this layer is corroded by acids such as hydrochloric acid and sulfuric acid, the reaction proceeds with the evolution of hydrogen gas. [1] [9] Zn + 2 H ...
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table.

2,3-Bisphosphoglyceric acid, which the Benesches discovered played a key role in the transport of oxygen by hemoglobin. Reinhold Benesch (August 13, 1919 – December 30, 1986) [1] and Ruth Erica Benesch (February 25, 1925 [2] –March 25, 2000 [3]) were American biochemists at Columbia University whose forty year scientific collaboration primarily investigated hemoglobin.

HCO − 3 + H + + 2NH + 4 +2OH − ↔ CO 3 −2 + 2NH + 4 + 2H 2 O (5) The produced carbonate ions precipitate in the presence of calcium ions as calcium carbonate crystals (6). Ca +2 + CO 3 −2 ↔ CaCO 3 (6) The formation of a monolayer of calcite further increases the affinity of the bacteria to the soil surface, resulting in the ...
