The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element ...

The atomic number ofiodine(53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 – 53 = 74). Does magnesi...

This ecto-nucleotidase pathway has an extremely fast activity, with a T1/2 of ∼200 ms for the conversion of ATP into adenosine (Dunwiddie et al., 1997). A number of enzymatic families contribute to this pathway, including the ecto-Ca2+/Mg2+ATPase (E-NTPase) and ecto-...
Atomic Number The amount of protons found in the nucleus. Element A pure substance made up of 1 type of atom. Molecule Two or more atoms joined (bonded) together, forming a small particle. Compound A substance made up of two or more different types of atoms that have been joined (bonded...
Recently, we identified the c subunit of the mitochondrial ATPase as a fundamental regulator of mPTP activity [74,75]. Of all the subunits that compose the FO complex (see above), the a, b and c subunits are sufficient to facilitate the translocation of protons across lipid bilayers, and ...

The overall rate of H/D exchange of the 2- and 3-protons in an acidic medium is ca. 1015 times greater than that observed for benzene and is subject to general acid catalysis 〈78JCS(P2)72, 80JCS(P2)110〉. The relative rate of α : β H/D exchange is generally between 1.0 and...
