NCIt definition : A purine ribonucleotide with hypoxanthine as the base and one phosphate group attached
to the sugar moiety. Inosinic acid and its salt forms are used as flavor enhancers
in industrial food production. In vivo, inosinic acid is involved in purine metabolism
and acts as an intermediate in the synthesis of adenine and guanine, which are precursors
for the second messenger signaling molecules adenosine monophosphate (AMP) and guanosine
monophosphate (GMP), respectively.;
