1. The Dalton ( Da ) is another name for the unified atomic mass unit.
2. Monoisotopic mass is typically expressed in unified atomic mass units ( u ), also called daltons ( Da ).
3. It is denoted with symbols " u " ( for unified atomic mass unit ) or " Da " ( for dalton ).
4. For comparison, the "'atomic mass "'of a carbon-12 atom is exactly 12 unified atomic mass units.
5. In this sense, most uses of the terms " atomic mass units " and " amu " today actually refer to unified atomic mass unit.
6. It's difficult to find unified atomic mass unit in a sentence. 用unified atomic mass unit造句挺難的
7. Relative isotopic mass is similar to atomic mass and has exactly the same numerical value as atomic mass, whenever atomic mass is expressed in unified atomic mass units.
8. Since the unified atomic mass unit is defined as 1 / 12 of the mass of 12 C the calibration of the magnetic field with carbon clusters allows absolute mass measurements.
9. Bovine ?-lactoglobulin is a relatively small protein of 162 residues, with an 18.4 kDa molecular weight ( 1 dalton being defined as 1 unified atomic mass unit ).
10. The unified atomic mass unit ( u ), 1 gram divided by Avogadro's number, is almost the mass of a hydrogen atom, which is mostly the mass of the proton.
11. where "'u "'represents the unified atomic mass unit, Da represents the unit dalton, and " e " represents the elementary charge which is the electric charge unit in the atomic unit system.
12. A number of authors have published criticisms of the revised definitions in particular that proposal had failed to address the impact of breaking the link between the dalton and the unified atomic mass unit, and the Avogadro constant and Avogadro's number.
13. Atomic masses expressed in unified atomic mass units ( i . e . relative isotopic masses ) are always close to whole-number values, but never ( except in the case of carbon-12 ) exactly a whole number, for two reasons:
14. This shift in nomenclature reaches back to the 1960s and has been the source of much debate in the scientific community, which was triggered by the adoption of the unified atomic mass unit and the realization that weight was in some ways an inappropriate term.
15. The mass number should also not be confused with the relative atomic mass ( also called atomic weight ) of an element, which is the ratio of the average atomic mass of the different isotopes of that element ( weighted by abundance ) to the unified atomic mass unit.
16. When compared to the average mass per nucleon in carbon-12, which is moderately strongly-bound compared with other atoms, the mass defect of binding for most atoms is an even smaller fraction of a dalton ( unified atomic mass unit, based on carbon-12 ).
