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 ...
Tripalmitin is a triglyceride derived from glycerol and three units of palmitic acid, commonly found in saturated fats.
Palmitoylcarnitine is an ester derivative of carnitine involved in the metabolism of fatty acids.During the tricarboxylic acid cycle (TCA), fatty acids undergo a process known as β-oxidation to produce energy in the form of ATP. β-oxidation occurs primarily within mitochondria, however the mitochondrial membrane prevents the entry of long chain fatty acids (>C10), so the conversion of fatty ...
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.
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.
The mass of b 2-ion = mass of two amino acid residues + 1. Table 2. Mass of b2-ions in peptide fragmentation [16] Identify a sequence ion series by the same mass difference, which matches one of the amino acid residue masses (see Table 1). For example, mass differences between a n and a n-1, b n and b n-1, c n and c n-1 are the same.

Mass-independent sulfur isotope fractionations are found to be widespread in the geologic record before about 2.45 billion years ago, and these isotopic signatures have since ceded to mass-dependent fractionation, providing strong evidence that the atmosphere shifted from anoxic to oxygenated at that threshold.
