Guanosine monophosphate

The chemical formula of guanine is C5H5N5O. It is one of the four nucleobases found in DNA and RNA, and it pairs with cytosine. Guanine is also an essential component of guanosine triphosphate (GTP) and guanosine monophosphate (GMP), which are involved in various cellular processes.

It also means guanosine monophosphate: a ribonucleotide constituent of ribonucleic acid that is the phosphoric acid ester of the nucleoside guanosine. And, a third, in the medical dictionary is:GMP (jē'ěm-pē') a noun: A nucleotide composed of guanine, ribose, and one phosphate group that is formed during protein synthesis. Also called guanine ribonucleotide, guanylic acid ========== GMP means Good Manufacturing Practices

Umami represents the taste of the amino acid L-glutamate and 5'-ribonucleotides such as guanosine monophosphate (GMP) and inosine monophosphate (IMP).[8] Although it can be described as a pleasant "brothy" or "meaty" taste with a long lasting, mouthwatering and coating sensation over the tongue. Umami has a mild but lasting aftertaste difficult to describe. It induces salivation and a sensation of furriness on the tongue, stimulating the throat, the roof and the back of the mouth

Guanosine is a purine nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N9-glycosidic bond and there are no anhydride bond in guanosine.
