Antioxidant action and effectiveness of sulfur-containing amino acid during deep frying.

H F Emilie Heng et al.

Journal of food science and technology, 57(3), 1150-1157 (2020-03-04)

The aim of the study was to solve the mystery why sulfur-containing amino acids such as methionine can perform as an antioxidant during frying and hypothesized the antioxidative mechanisms. The results of this study revealed that sulfur-containing amino acids such

High-precision position-specific isotope analysis of 13C/12C in leucine and methionine analogues.

Gavin L Sacks et al.

Analytical chemistry, 75(20), 5495-5503 (2004-01-09)

We report an automated method for high-precision position-specific isotope analysis (PSIA) of carbon in amino acid analogues. Carbon isotope ratios are measured for gas-phase pyrolysis fragments from multiple sources of 3-methylthiopropylamine (3MTP) and isoamylamine (IAA), the decarboxylated analogues of methionine

Photodissociation of S atom containing amino acid chromophores.

Ming-Fu Lin et al.

The Journal of chemical physics, 127(6), 064308-064308 (2007-08-21)

Photodissociation of 3-(methylthio)propylamine and cysteamine, the chromophores of S atom containing amino acid methionine and cysteine, respectively, was studied separately in a molecular beam at 193 nm using multimass ion imaging techniques. Four dissociation channels were observed for 3-(methylthio)propylamine, including

Adducts of Rh2[MTPA]4 with some phosphine chalcogenides: nature of binding and ligand exchange.

Tamás Gáti et al.

Magnetic resonance in chemistry : MRC, 42(7), 600-604 (2004-06-08)

Adducts of four phosphine chalcogenides with the chiral dirhodium complex ([Rh-Rh]) were investigated by variable-temperature 1H and 31P NMR spectroscopy in order to compare their properties as axial ligands. Whereas the selenide (1) and the sulfide (2) are strong ligands

Time-resolved chemically induced dynamic nuclear polarization studies of structure and reactivity of methionine radical cations in aqueous solution as a function of pH.

Olga B Morozova et al.

The journal of physical chemistry. A, 109(45), 10459-10466 (2006-07-13)

Using time-resolved chemically induced dynamic nuclear polarization (CIDNP) techniques, we have studied the mechanism of the photoreactions of triplet excited 4-carboxybenzophenone (CBP) with l-methionine (Met) and 3-(methylthio)propylamine (MTPA) in aqueous solution and the details of the formation of CIDNP at

Inhibition by polyamines of methylthiopropylamine-induced ornithine decarboxylase in human lymphoid leukemia Molt 4B cells.

H Hibasami et al.

Biochemical pharmacology, 38(21), 3673-3676 (1989-11-01)

Methylthiopropylamine (MTPA), an inhibitor of spermidine synthase, markedly induced ornithine decarboxylase (ODC) activity (about 30-fold of the basal level) in human lymphoid leukemia Molt 4B cells. This induction was blocked by the addition of spermidine, spermine or putrescine simultaneously with

Methylthiopropylamine, a potent inhibitor of spermidine synthase and its antiproliferative effect on human lymphoid leukemia Molt 4B cells.

H Hibasami et al.

Anticancer research, 7(6), 1213-1216 (1987-11-01)

The catalytic activity of spermidine synthase isolated from rat ventral prostate was significantly inhibited by methylthiopropylamine (MTPA). Spermine synthase was almost insensitive to this inhibitor. Inhibition of spermidine synthase by MTPA was competitive with respect to a substrate putrescine (Ki
