Purification and identification of antioxidative peptides from loach (Misgurnus anguillicaudatus) protein hydrolysate by consecutive chromatography and electrospray ionization-mass spectrometry

Loach protein was hydrolyzed by papain to obtain antioxidative peptides. The results showed that the loach protein hydrolysate (LPH) could scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) (IC50 =17.0?0.54mg/mL) and hydroxyl radicals (IC50 =2.64?0.29mg/mL).

Analyses for phosphatidylcholine hydroperoxides by LC/MS

1?1.0pmol). The limit of detection (LOD) (S/N=3:1) was 0.01pmol, and the limit of quantification (LOQ) (S/N=6:1) was 0.1pmol for both PC 16:0/18:2-OOH and PC 18:0/18:2-OOH. Plasma concentrations of PC 16:0/18:2-OOH and PC 18:0/18:2-OOH were 89 and 32nM, respectively, in a healthy volunteer.

DE‐loop mutations affect β2 microglobulin stability, oligomerization, and the low‐pH unfolded form

?2 microglobulin (?2m) is the light chain of class?I major histocompatibility complex (MHC?I). Its accumulation in the blood of patients affected by kidney failure leads to amyloid deposition around skeletal joints and bones, a severe condition known as Dialysis Related Amyloidosis (DRA).

Bismuth binding studies to the human metallothionein using electrospray mass spectrometry

Bismuth compounds are currently used to treat gastric ailments and to prevent the toxic side effects of cancer treatments. The affinity of bismuth for binding to sulfur compounds has been reported and one such target biomolecule is the cysteine-rich metalloprotein metallothionein.

Functionalization of Fullerenes with Cyclopentadienyl and Anthracenyl Capped Polymeric Building Blocks via Diels-Alder Chemistry

Similarly, anthracenyl capped PEGs react with fullerenes (in a 1:3 molar ratio) in DA reactions to yield the corresponding hybrids, albeit over a period of 1.5 h at 80 ?C and a lesser conversion.

Kinetics of an enzyme-catalyzed reaction measured by electrospray ionization mass spectrometry using a simple rapid mixing attachment

Mass spectrometry offers a potential means of measuring virtually all enzyme-catalyzed reactions by simultaneously measuring the concentrations of substrates, products, and intermediates where there are differences in mass between them.

Degradation of Poly(butyl acrylate) and Poly(2-hydroxyethyl methacrylate) Model Compounds Under Extreme Environmental Conditions

The degradation of low-MW ($\overline {M} _{n} $ = 1 500 g ? mol-1) model compounds of pBA and pHEMA were studied under conditions corresponding to the worst-case temperatures and irradiation intensities likely to be experienced by a surface coating exposed to the harsh Australian environment.
