The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is defined as one newton per square metre. It is named after the French polymath Blaise Pascal.
Phosphate Ester Fluids - Benefits and Limitations. Since the discovery of their excellent anti-wear and fire resistance properties in the 1940s, the use of phosphate esters by industry has steadily increased. Phosphate esters are used primarily as fire-resistant basestocks in several applications including hydraulic systems, turbines and compressors.
Substrate Level Phosphorylation. Donation of inorganic phosphate (Pi) from specific organic compounds to ADP to form ATP. Substrate-Level Phosphorylation is simply the enzymatic transfer of a phosphate group from an organic molecule to adenosine diphosphate (ADP) to form adenosine triphosphate (ATP). The production of ATP from ADP requires addition, via a condensation reaction, of a single phosphate (PO43-) to the latter.
