Identification
Name:Inosinic acid
Description:Inosinic acid is a purine nucleotide which has hypoxanthine as the base and one phosphate group esterified to the sugar moiety. It is formed by the deamination of AMP and when hydrolysed produces inosine. Inosinic acid is the ribonucleotide of hypoxanthine and is the first compound formed during the synthesis of purine.
