That is, the molar mass of a chemical compound expressed in g/mol or kg/kmol is numerically equal to its average molecular mass expressed in Da. For example, the average mass of one molecule of water is about 18.0153 Da, and the mass of one mole of water is about 18.0153 g.
For example, water has a molar mass of 18.0153(3) g/mol, but individual water molecules have molecular masses which range between 18.010 564 6863(15) Da (1 H 2 16 O) and 22.027 7364(9) Da (2 H 2 18 O). Atomic and molecular masses are usually reported in daltons, which is defined in terms of the mass of the isotope 12 C (carbon-12).
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
Molecular chaperones are a diverse family of proteins that function to protect proteins from irreversible aggregation during synthesis and in times of cellular stress.The bacterial molecular chaperone DnaK is an enzyme that couples cycles of ATP binding, hydrolysis, and ADP release by an N-terminal ATP-hydrolyzing domain to cycles of sequestration and release of unfolded proteins by a C ...
The most common use of 'Daltons' is as a synonym for g/mol. When someone talks about a 254 kDa protein, they mean it has a molecular mass of 254,000 g/mol. I think this article needs to make this clear.27.54.43.66 03:46, 28 May 2011 (UTC) The statement "Da = g/mol" occurs often in chemistry texts and elsewhere.

From March 2009 to December 2012, if you bought shares in companies when Richard A. Gephardt joined the board, and sold them when he left, you would have a 369.9 percent return on your investment, compared to a 85.6 percent return from the S&P 500.
It has a molecular weight of about 40 kDa and is localized to the outer membrane, through which it allows both inorganic and organic ions to pass. The addition of Protein K in the outer membrane proven to cause an increased rate of uptake of nutrients and a faster growth rate relative to the parental porin- strain. [2]
