Abstract UV/Vis absorption spectroelectrochemistry is a very promising analytical technique due to the complementary information that simultaneously obtained from electrochemistry and spectroscopy. In this work, used in parallel configuration study oxidation of folic acid alkaline medium. Herein, has been detect both products consumed at electrode/solution interface, allowing us develop an prot...

This study dealt with the phytochemical and vitamin constituents of Sennaoccidentalis (Uzakimma). The qualitative analysis plant indicated presence high flavonoids, glycosides, alkaloids, terpenoids and, moderate tannins, saponin, steroids, phenol. quantitative results were tannins 1.4775 ± 0.0495 mg/g, alkaloids 2.2280 0.0283 saponin 1.5830 0.0141 glycosides 2.1295 0.1909 2.7560 0.1414 flavono...

The 9-23 amino acid region of the insulin B chain (B9-23) is a dominant epitope recognized by pathogenic T lymphocytes in nonobese diabetic mice, the animal model for type 1 diabetes. We describe herein similar (B9-23)-specific T-cell responses in peripheral lymphocytes obtained from patients with recent-onset type 1 diabetes and from prediabetic subjects at high risk for disease. Short-term T-...

Vitamins are essential for a healthy life. Compared to other nutrients, the body needs them in very small amounts. B vitamins, often known as vitamin complex, class of water-soluble vitamins with key functions cellular metabolism. Thiamine (vitamin B1), riboflavin B2), niacin B3), pantothenic acid B5), pyridoxine B6), biotin B7), folate B9), folic acid, and cobalamin B12) eight distinct that co...

Genome-scale models (GEMs) of metabolism were constructed for 55 fully sequenced Escherichia coli and Shigella strains. The GEMs enable a systems approach to characterizing the pan and core metabolic capabilities of the E. coli species. The majority of pan metabolic content was found to consist of alternate catabolic pathways for unique nutrient sources. The GEMs were then used to systematicall...

Homocysteine is a sulfur-containing amino acid, which is synthesized from the precursor methionine through a multi-step process, and then reconverted to methionine or catabolyzed into cysteine. The presence of vitamin B9 (folic acid), vitamin B6 (pyridoxine) and vitamin B12 (cobalamin) is essential in homocysteine metabolism, wherein defi ciency of one or more of these nutrients is associated w...
