Molecular Weight Description

The L-arginine molecule consists of 14 Hydrogen atom(s), 6 Carbon atom(s), 4 Nitrogen atom(s), and 2 Oxygen atom(s) - a total of 26 atom(s). The molecular weight of L-arginine is determined by the sum of the atomic weights of each constituent element multiplied by the number of atoms, which is calculated to be:

$$ 174.20096 · \frac{g}{mol} $$

The exact term of the above molecular weight is “molar mass”, which is based on the atomic mass of each element. Molecular weight is actually an older term of “relative molar mass” or “molecular mass”, which is a dimensionless quantity equal to the molar mass divided by the molar mass constant defined by 1 g/mol.

Molecular masses are calculated from the standard atomic weights of each nuclide, while molar masses are calculated from the atomic mass of each element. The atomic mass takes into account the isotopic distribution of the element in a given sample.

Additional Information for Identifying L-arginine Molecule

  • Structure Data File (SDF/MOL File) of L-arginine

    The structure data file (SDF/MOL File) of L-arginine is available for download in the SDF page of L-arginine, which provides the information on atoms, bonds, connectivity and coordinates of L-arginine. The L-arginine structure data file can be imported to most of the chemistry-related software, providing three-dimensional visualization and further analysis.

  • Chemical structure of L-arginine

    The molecular structure image of L-arginine is available in chemical structure page of L-arginine, which provides the molecular geometry information, i.e., the spatial arrangement of atoms in L-arginine and the chemical bonds that hold the atoms together.

  • Chemical formula of L-arginine

    The molecular formula of L-arginine is given in chemical formula page of L-arginine, which identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element.

  • InChI (IUPAC International Chemical Identifier) information of L-arginine

    In addition to the molecular weight information, the structural information of L-arginine in a textual expression is available via InChi. The full standard InChI of L-arginine is given below:

    InChI=1S/C6H14N4O2/c7-4(5(11)12)2-1-3-10-6(8)9/h4H,1-3,7H2,(H,11,12)(H4,8,9,10)/t4-/m0/s1

    It can provide a way to encode the molecular information of L-arginine to facilitate the search for the compound information in databases and on the web.

    The condensed, 27 character standard InChIKey (hashed version of the full standard InChI) of L-arginine is:

    InChIKey=ODKSFYDXXFIFQN-BYPYZUCNSA-N

    It may allow easier web searches for L-arginine. The InChIKey, however, needs to be linked to the full InChI as well in order to get back to the original structure of the L-arginine as the full standard InChI cannot be reconstructed from the InChIKey.
