  2. Monoisotopic mass - Wikipedia

    en.wikipedia.org/wiki/Monoisotopic_mass

    The monoisotopic mass is very useful when analyzing small organic compounds since compounds with similar weights will not be differentiated if the nominal mass is used. For example, when comparing tyrosine which has a molecular structure of C 9 H 11 NO 3 with a monoisotopic mass of 182.081 Da and methionine sulphone C 5 H 11 NO 4 S which ...

  3. Palmitic acid - Wikipedia

    en.wikipedia.org/wiki/Palmitic_acid

    Palmitic acid (hexadecanoic acid in IUPAC nomenclature) is a fatty acid with a 16-carbon chain. It is the most common saturated fatty acid found in animals, plants and microorganisms. [ 9 ] [ 10 ] Its chemical formula is CH 3 (CH 2 ) 14 COOH , and its C:D ratio (the total number of carbon atoms to the number of carbon-carbon double bonds) is 16:0.

  7. Loss on ignition - Wikipedia

    en.wikipedia.org/wiki/Loss_on_ignition

    Loss on ignition (LOI) is a test used in inorganic analytical chemistry and soil science, particularly in the analysis of minerals and the chemical makeup of soil. It consists of strongly heating a sample of the material at a specified temperature, allowing volatile substances to escape, until its mass ceases to change. This may be done in air ...

  8. Mass (mass spectrometry) - Wikipedia

    en.wikipedia.org/wiki/Mass_(mass_spectrometry)

    The monoisotopic mass is the sum of the masses of the atoms in a molecule using the unbound, ground-state, rest mass of the principal (most abundant) isotope for each element. [12] [5] The monoisotopic mass of a molecule or ion is the exact mass obtained using the principal isotopes. Monoisotopic mass is typically expressed in daltons.

  9. Dipalmitoylphosphatidylcholine - Wikipedia

    en.wikipedia.org/wiki/Dipalmitoylphosphatidylcholine

    Dipalmitoylphosphatidylcholine (DPPC) is a phospholipid (and a lecithin) consisting of two C 16 palmitic acid groups attached to a phosphatidylcholine head-group.. It is the main constituent of pulmonary surfactants, which reduces the work of breathing and prevents alveolar collapse during breathing.
