Chemical Information
NameInosinic acid
DescriptionInosinic acid, also known as 5'-inosinate or 5'-IMP, belongs to the class of organic compounds known as purine ribonucleoside monophosphates. These are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. Inosinic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Inosinic acid exists in all living species, ranging from bacteria to humans. Within humans, inosinic acid participates in a number of enzymatic reactions. In particular, inosinic acid can be converted into phosphoribosyl formamidocarboxamide through the action of the enzyme bifunctional purine biosynthesis protein purh. In addition, inosinic acid can be converted into xanthylic acid through its interaction with the enzyme inosine-5'-monophosphate dehydrogenase 1. In humans, inosinic acid is involved in the metabolic disorder called the gout or kelley-seegmiller syndrome pathway. Inosinic acid is an odorless tasting compound. Outside of the human body, Inosinic acid has been detected, but not quantified in, several different foods, such as hickory nuts, turnips, pepper (spice), mountain yams, and muskmelons. This could make inosinic acid a potential biomarker for the consumption of these foods. A purine ribonucleoside 5'-monophosphate having hypoxanthine as the nucleobase.
