News Acids

• Bacterium breaks down grass into biofuel

  Research reports the discovery of the first microorganism that anaerobically degrades plant biomass, without the need for chemical pre-treatment, to produce raw materials that can be converted to biofuels. Scientists in the United States demonstrated that Caldicellulosiruptor bescii bacterium was ab more

• Simple synthesis of heavy oxygen-labelled alcohols

  Research reports a novel and extremely simple method for synthesising 18O-labelled alcohols using commercial boronic acids and a reagent prepared from elemental fluorine. Alcohols labelled with 18O are very valuable as biological probes for a variety of studies which are often limited by the availa more

• Detecting mirror molecules

  Harvard physicists have developed a novel technique that can detect molecular variants in chemical mixtures – greatly simplifying a process that is one of the most important, though time-consuming, processes in analytical chemistry. As described in a paper in Nature, post-doctoral researcher David P more

• Pressure Digestion for Sample Preparation
  

  What analyst does not wish for a universal method for processing all his or her samples? Pressure digestion represents just such a procedure for sample digestions and is therefore one of the standard sample preparation procedures currently employed in analytical chemistry for element quantification more

• A Platform System for Microwave Sample Preparation
  

  Today's technology enables the near-perfect determination of trace elements in all concentrations down to the ultra trace range. Modern AAS, ICP-OES, ICP-MS or electrochemical procedures such as voltammetry are reliable and accurate measuring methods for almost every type of task. However, in most cases the sample material has to be supplied in a suitable, measurable form, i.e. as a largely matrix-free solution without contamination or loss of analytes more

• ORAC Assay Performed on the POLARstar Omega and PHERAstar FS microplate reader
  

  In all oxygen consuming cells, metabolism and oxidative stress generate several intermediates and byproducts that are collectively known as reactive oxygen species (ROS). ROS are necessary intermediates in the human body, but they are also involved in the aging process and in the development of many degenerative diseases, including cancer, heart disease, Alzheimer's and Parkinson's. Herein we describe the determination of the antioxidant capacity of different fruit juices using the ORAC assay; a standardized method that uses Trolox®, a water-soluble analogue of vitamin E, as a standard substance more

• Zymogen activation of neurotrypsin and neurotrypsin-dependent agrin cleavage on the cell surface are enhanced by glycosaminoglycans

  The serine peptidase neurotrypsin is stored in presynaptic nerve endings and secreted in an inactive zymogenic form by synaptic activity. After activation, which requires activity of postsynaptic NMDA (N-methyl-D-aspartate) receptors, neurotrypsin cleaves the heparan sulfate proteoglycan agrin at a more

• New insights into the catalytic mechanism of histidine phosphatases revealed by a functionally essential arginine residue within the active site of the Sts phosphatases

  Sts (suppressor of T-cell receptor signalling)-1 and Sts-2 are HPs (histidine phosphatases) that negatively regulate TCR (T-cell receptor) signalling pathways, including those involved in cytokine production. HPs play key roles in such varied biological processes as metabolism, development and intr more

• Synthesis and reactivity of 5-polyfluoroalkyl-5-deazaalloxazines

  Reaction of 6-arylamino-1,3-dialkyluracils with anhydrides of polyfluorocarboxylic acids in the presence of pyridine and subsequent cyclization with concentrated H2SO4 gave the corresponding 1,3-dialkyl-5-(polyfluoroalkyl)pyrimido[4,5-b]quinoline-2,4(1H,3H)-diones (5-polyfluoroalkyl-5-deazaalloxazin more
