Time-resolved chemically induced dynamic nuclear polarization (CIDNP) was applied to the investigation of the photo-oxidation of two sulfur containing peptides, glycylmethionine (Gly-Met) and methionylglycine (Met-Gly). It was established that the reaction of Gly-Met with a photosensitizer, triplet 4-carboxybenzophenone, occurs via

Radical cations [Met-Gly](•+), [Gly-Met](•+), and [Met-Met](•+) have been generated through collision-induced dissociation (CID) of [Cu(II)(CH3CN)2(peptide)](•2+) complexes. Their fragmentation patterns and dissociation mechanisms have been studied both experimentally and theoretically using density functional theory at the UB3LYP/6-311++G(d,p) level. The captodative structure
Crystallographic analysis of a solid solution of two diastereoisomers, i.e. ({(1S,R)-1-carboxy-3-[(R,S)-methylsulfinyl]propyl}aminocarbonyl)methanaminium tetrachloridoaurate(III) and ({(1S,R)-1-carboxy-3-[(S,R)-methylsulfinyl]propyl}aminocarbonyl)methanaminium tetrachloridoaurate(III), (C(7)H(15)N(2)O(4)S)[AuCl(4)], has shown that in the presence of gold(III), the methionine part of the Gly-D,L-Met dipeptide is oxidized to sulfoxide, and no coordination to the

Dinuclear platinum(II) complexes, [{Pt(en)Cl}2(μ-qx)]Cl2·2H2O (1), [{Pt(en)Cl}2(μ-qz)](ClO4)2 (2), and [{Pt(en)Cl}2(μ-phtz)]Cl2·4H2O (3), were synthesized and characterized by different spectroscopic techniques. The crystal structure of 1 was determined by single-crystal X-ray diffraction analysis, while the DFT M06-2X method was applied in order to

The absorption of carnosine, methionine, and methionylglycine (using 35S-methionine and 35S-methionylglycine as representative markers) across ruminal and omasal epithelia collected from four (carnosine) and seven sheep (methionine and methionylglycine) were studied using parabiotic chambers that were repeatedly sampled over a
