JOURNAL FREE ACCESSL-Ascorbic acid 2-phosphate (Asc 2-P), a long-acting vitamin C derivative, stimulates collagen accumulation, cell proliferation, and formation of a three-dimensional tissue (dermis) by skin fibroblasts. Investigation of molecular mechanisms of Asc 2-P action indicated that it stimulates maturation of extracellular matrix (ECM) by activating transcription of genes for type I collagen which form a back-bone structure of the ECM. Asc 2-P also stimulates differentiation and maintains differentiated phenotypes of various kinds of cells of epithelial and mesenchymal origin. Asc 2-P may be useful to clarify new physiological functions of vitamin C and investigation of the molecular mechanisms.View full abstractDownload PDF (1781K) -

JOURNAL FREE ACCESSIn order to obtain reliable values of vitamin B_6 contents in some foods and food materials by microbioassay, it is critical to hydrolyze the samples satisfactorily prior to the determination .The conditions for the acid hydrolysis of samples were investigated with some plant and animal foods. It was found that pure pyridoxine-β-glucoside (PN-β-Glu), which was found in some plant foods, was hydrolyzed at 121℃ for 2 h with 0.88 N-HCl. Food samples from plant origins, to release pyridoxine (PN) completely from some plant matrix, must be hydrolyzed stronger conditions than the reported one, that a sample was hydrolyzed at 121℃ for 2 h with 0.44 N-HCl. It was also found that hydrolysis by HCl was rather suitable for the plant foods than by sulfuric acid. To save the time, three hour autocleave at 121℃ with 0.88 N-HCl for plant foods, and with 0.11 N-HCl for animal foods, was newly proposed as the conditions for the hydrolysis of foods satisfactorily.View full abstractDownload PDF (705K) -
