B Battery: Eveready 762-S: 45 V: Threaded posts H: 146 L: 104.8 W: 63.5 Used to supply plate voltage in vintage vacuum tube equipment. Origin of the term B+ for plate voltage power supplies. Multiple B batteries may be connected in series to provide voltages as high as 300 V DC. Some versions have a tap at 22.5 volts. GB Battery: C Battery ...
A zinc-carbon rectangular battery, consisting of 6 flat "size 22" cells. Equivalent to a PP3 or transistor battery. 6P222/162: 6: P: 222: 162: A zinc-carbon battery, maximum dimensions: length 192 mm, width 113 mm, and height 162 mm. Consisting of 6 cells in series. CR17345: C: R: 17: 345: A single-cell round lithium cell, 17 mm diameter, 34.5 ...
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion. As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here. [64]
D cell batteries, wooden matchstick for scale. A D battery (D cell or IEC R20) is a standardized size of a dry cell. A D cell is cylindrical with an electrical contact at each end; the positive end has a nub or bump. D cells are typically used in high current drain applications, such as in large flashlights, radio receivers, and transmitters ...

N-acetylphosphatidylethanolamine-hydrolysing phospholipase D (EC 3.1.4.54, NAPE-PLD, anandamide-generating phospholipase D, N-acyl phosphatidylethanolamine phospholipase D, NAPE-hydrolyzing phospholipase D) is an enzyme with systematic name N-acetylphosphatidylethanolamine phosphatidohydrolase. [1] [2] It catalyses the following chemical reaction
A hydrophobic cavity in NAPE-PLD provides an entryway for the substrate NAPE into the active site, where a binuclear zinc center orchestrates its hydrolysis. Unexpectedly, the structure unveils bile acids bind the membrane enzyme, enhancing dimer assembly and enabling catalysis.
N-acyl phosphatidylethanolamine phospholipase D (NAPE-PLD) is an enzyme that catalyzes the release of N-acylethanolamine (NAE) from N-acyl-phosphatidylethanolamine (NAPE). This is a major part of the process that converts ordinary lipids into chemical signals like anandamide and oleoylethanolamine .
