Do zwitterionic species exist in the non-enzymatic peptide bond formation?
2012
The use of proper computational methods and models has allowed answering the controversial question of whether zwitterionic species exist in the mechanism of peptide bond synthesis in aqueous solution. In fact, the different conformations of zwitterionic species open the door to different mechanistic paths.
Non-Enzymatic Water-Soluble Antioxidants Bioanalysis in Some Teas and Juices by PCL Method
2011
Non-enzymatic water-soluble antioxidants from different teas (black, green, peppermint), coffee, natural extract of rosemary and fruit juices (apple, grape, grapefruit, kiwifruit) were quantized by measuring their chemiluminescence in order to establish their power to protect the living beings from the free radicals. Among the samples high values of antioxidative capacity presents green tea (655 mmol AU) (AU=ascorbic units) and kiwi fruit juice (31 mmol AU). The maximum measuring times are less than 3 minutes. The sensivity of the photo-induced chemiluminescence (PCL) method was very high: nanomolar concentrations of non-enzymatic watwer-soluble antioxidative substances, as ascorbic acid un…
