Application
- 采用ORAC和TOSC法测定抗氧化能力。本研究详细介绍了α-酮-γ(甲硫基)丁酸钠盐在ORAC和TOSC测定法评估抗氧化能力中的应用，强调了其在代谢和化学合成研究中的作用（Garrett AR et al., 2010）。
General description
α-酮-γ-甲硫丁酸(KMTB)是L-甲硫氨酸的酮衍生物，作为L-甲硫氨酸的替代物具有较大潜力。KMTB的钠盐可用于亲核取代反应。还可作为合成砌块制备氨基酸、多肽等复杂有机物。

D-Methionine was converted to L-methionine in a reaction system where four enzymes were used. D-amino acid oxidase (D-AAO) from Arthrobacter protophormiae was used for the complete conversion of D-methionine to 2-oxo-4-methylthiobutyric acid. Catalase was added to prevent 2-oxo-4-methylthiobutyric acid decarboxylation.

The present study investigated the proposed involvement of contaminant-stimulated reactive oxygen species (ROS) production in disease processes in fish. NAD(P)H-dependent ROS production of subcellular fractions was determined by the iron/EDTA-mediated oxidation of 2-keto-4-methiolbutyric acid. Hepatic cytosolic NADPH-dependent and microsomal NAD(P)H-dependent

Two enzymes, designated, E-2 and E-2', catalyze different oxidation reactions of an aci-reductone intermediate in the methionine salvage pathway. E-2 and E-2', overproduced in Escherichia coli from the same gene, have the same protein component. E-2 and E-2' are separable

Glucosinolates are a group of sulfur-rich thioglucoside natural products common in the Brassicaceae and related plant families. The first phase in the formation of many glucosinolates involves the chain extension of the amino acid methionine. Additional methylene groups are inserted

During embryogenesis in grass shrimp the capacity to scavenge oxyradicals increased as measured by the Total Oxyradical Scavenging Capacity (TOSC) assay. The increase in TOSC during embryogenesis was associated with increasing concentrations of a number of antioxidants, including coenzyme Q
