| Research Abstract |
New metabolic pathways involved in the synthesis of inosinate and guanylate were investigated. Shiitake mushrooms(Lentinula edodes), cultured Japanese jack mackerel(Trachurus japonicus) and Japanese radish(Raphanus sativus) were chosen as the representatives of mushrooms, fishes and vegetables, respectively. Metabolic profiles of purine ribonucleotides in these foods were examined based on the in situ metabolic fate of radio-labelled precursors and the in vitro activities of enzymes. Inosinate and guanylate were synthesized via salvage pathways in all foods. It was suggested that salvage pathways were operative in these foods under certain conditions of cooking, processing and preservation.
