Phosphoenolpyruvate (2-phosphoenolpyruvate, PEP) is the carboxylic acid derived from the enol of pyruvate and phosphate. It exists as an anion. PEP is an important intermediate in biochemistry. It has the highest-energy phosphate bond found (−61.9 kJ/mol) in organisms, and is involved in glycolysis and gluconeogenesis.
The HSSF component is the most advanced feature of the library. [11] Other components (HPSF, HWPF, and HSLF) are usable, but less full-featured. [12] [13] The POI library is also provided as a Ruby [14] or ColdFusion extension. There are modules for Big Data platforms (e.g. Apache Hive/Apache Flink/Apache Spark), which provide certain ...
It takes in spectra in supported input formats and writes out .pep.xml, .pin.xml, .sqt and/or .out files.

Phosphoenolpyruvate carboxylase (also known as PEP carboxylase, PEPCase, or PEPC; EC 4.1.1.31, PDB ID: 3ZGE) is an enzyme in the family of carboxy-lyases found in plants and some bacteria that catalyzes the addition of bicarbonate (HCO 3 −) to phosphoenolpyruvate (PEP) to form the four-carbon compound oxaloacetate and inorganic phosphate: [1]
Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).
The first issue of The Computer Journal published by The British Computer Society appeared in mid 1958. [ 9 ] The UK Accountancy Body now named The Association of Chartered Certified Accountants formed an Electronic Data Processing Committee in July 1958 with the purpose of informing its members of the opportunities created by the computer.

A spreadsheet is essentially just one table, whereas a database is a collection of many tables with machine-readable semantic relationships. While it is true that a workbook that contains three sheets is indeed a file containing multiple tables that can interact with each other, it lacks the relational structure of a database.
An example of a data-integrity mechanism is the parent-and-child relationship of related records. If a parent record owns one or more related child records all of the referential integrity processes are handled by the database itself, which automatically ensures the accuracy and integrity of the data so that no child record can exist without a parent (also called being orphaned) and that no ...
