A fluorescent probe (N-(4-methyl-2-oxo-2H-chromen-7-yl)-2,4-dinitrobenzenesulfonamide), which exhibits high selectivity to glutathione and cysteine among amino acids including sulphur-containing methionine and metal ions, was synthesized. The experiments demonstrate that the fluorescent probe is a reliable and specific probe for glutathione and cysteine in living cells.

Sulphur (S) and selenium (Se) are chemically similar. Once Se is taken up, it substitutes S in S-containing amino acids. This study investigated the effect of on selenite accumulation microalga Nannochloropsis oceanica. [0–28 mM] concentrations 0 30 μM were tested. ≤ 3 mM led to decreased cell growth whereas cultures with ≥ 4 not limited. increased up 8-fold when using 2 28 mM. The average rela...

Common bean (Phaseolus vulgaris L.) is one of the most important grain legume foods for human diet. seed gaining attention due to its content secondary metabolites with positive effects on health. The present work analysed effect common germination essential amino acid profile, active compound content, and expansion index after extrusion processing. tryptophan (Trp) in raw (RCB) germinate...

The amino acids profiles were determined in the whole eggs of duck, francolin and turkey consumed in Nigeria on a dry weight basis. The protein content (g/100 g) had the trend: francolin (80.1) > turkey (77.6) > duck (67.9). The highest concentrated amino acid in the three eggs was glutamic acid with values of (g/100 g): duck (13.1) > francolin (13.0) > turkey (12.1); with total amino acid foll...

CONTEXT Dietary proteins and amino acids can modulate pancreatic function. OBJECTIVE Our aim was to estimate the levels of plasma amino acids in chronic pancreatitis patients and study their relationship with disease characteristics as well as exocrine and endocrine insufficiency. PATIENTS One hundred and seventy-five consecutive adult patients with chronic pancreatitis: 84 patients with al...

Tribolium castaneum can survive in extremely dry environments and be one of the major insect pests broken processed grains or other stored dried foods. Additionally, this species has demonstrated resistance to some classes insecticides. The objective work was evaluate nutritional chemical composition T. castaneum, reared on maize flour, compare protein, lipids fatty acids profile, amino mineral...

The sulphate assimilation pathway provides reduced sulphur for the synthesis of the amino acids cysteine and methionine. These are the essential building blocks of proteins and further sources of reduced sulphur for the synthesis of coenzymes and various secondary compounds. Several recent reports identified the adenosine 5'-phosphosulphate reductase (APR) as the enzyme with the greatest contro...

TiH distribution of sulphur in protein has long been a subject of interest, and the work of Osborne and numerous other investigators on the sulphur in vegetable proteins indicated the probable presence of at least two forms of organic sulphur; further, Dakin [1920] in his amino-acid analysis of gelatin found sulphur compounds other than cystine. The isolation of methionine [Mueller, 1921] and i...
