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 ...
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.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
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.

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.
KF is selective for water, because the titration reaction itself consumes water. In contrast, measurement of mass loss on drying will detect the loss of any volatile substance. However, the strong redox chemistry ( SO 2 /I 2 ) means that redox-active sample constituents may react with the reagents.
Monoisotopic mass is the sum of the masses of the atoms in a molecule using the most abundant isotope for each element; Monoisotopic element is one of the 26 chemical elements which have only one stable isotope
