A Dynamic Programming Approach to De Novo Peptide Sequencing via Tandem Mass Spectrometry [PDF]

open access: green, 2001
The tandem mass spectrometry fragments a large number of molecules of the same peptide sequence into charged prefix and suffix subsequences, and then measures mass/charge ratios of these ions.

Electrospray tandem mass spectrometry of aminochromes [PDF]

open access: bronzeRapid Communications in Mass Spectrometry, 2001
AbstractThe catecholamines adrenaline, noradrenaline, dopamine, dopa and isoprenaline were oxidized into their respective aminochromes: adrenochrome, noradrenochrome, dopaminochrome, dopachrome and isoprenochrome. Tandem mass spectrometry (MS/MS) fragmentation patterns were examined for the five aminochromes in order to establish a general structural ...

Simultaneous Method for Selected PBDEs and HBCDDs in Foodstuffs Using Gas Chromatography—Tandem Mass Spectrometry and Liquid Chromatography—Tandem Mass Spectrometry

open access: yesToxics, 2022
Flame retardants are added to consumer products to retard the ignition of combustible materials. Technical mixtures of polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCDD) were massively used for several decades.

Lipid Peroxidation in Algae Oil: Antagonist Effects of Natural Antioxidants

open access: yesMolecules, 2022
Tandem mass spectrometry is proposed to check lipid oxidation, a free radical-mediated phenomenon which effects oxidative deterioration in polyunsaturated fatty acids. Antioxidants are used by the food industry to delay the oxidation process.
