Saturated and unsaturated compounds having sweet, salt or umami taste enhancement qualities. An illustrative storage system includes a complex programmable logic device that interfaces with a memory controller and a basic input output system for ensuring that the system memory is maintained in a self refresh state in the event of an error condition. The wall panels allow concrete columns and beams to be formed in any size and shape. This intermediate voltage level is used in a state retention mode in which the clock signal clk to the logic block is stopped and state signal values are maintained therein using this reduced virtual power rail derived voltage difference. Compounds of the invention are nucleic acid-based and preferably comprise 2, 3, 4, 5 or 6 nucleoside units.
