Guanosine monophosphate (GMP), also known as 5′-guanidylic acid or guanylic acid (conjugate base guanylate), is a nucleotide that is used as a monomer in RNA. It is an ester of phosphoric acid with the nucleoside guanosine. GMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase guanine; hence it is a ribonucleotide ...
Xanthosine monophosphate (xanthylate) is an intermediate in purine metabolism. [1] It is a ribonucleoside monophosphate.It is formed from IMP via the action of IMP dehydrogenase, and it forms GMP via the action of GMP synthase.
GMP synthase forms a tetramer in an open box shape, which is a dimer of dimers. The R interfaces are held together with a hydrophobic core and a beta sheet , while the P dimer interfaces do not have a hydrophobic core and are more variable than the R interfaces. [ 1 ]
Cyclic guanosine monophosphate (cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP). cGMP acts as a second messenger much like cyclic AMP.Its most likely mechanism of action is activation of intracellular protein kinases in response to the binding of membrane-impermeable peptide hormones to the external cell surface.

Current good manufacturing practices (cGMP) are those conforming to the guidelines recommended by relevant agencies. Those agencies control the authorization and licensing of the manufacture and sale of food and beverages , [ 1 ] cosmetics , [ 2 ] pharmaceutical products , [ 3 ] dietary supplements , [ 4 ] and medical devices .

Analytical and clinical chemistry testing. Safety testing data must be submitted to regulatory authorities for product marketing authorization. During the review process, the submitted data undergoes verification to ensure compliance with Good Laboratory Practice (GLP) standards.
The history of discrete sample analysis for the clinical laboratory began with the introduction of the "Robot Chemist" invented by Hans Baruch and introduced commercially in 1959 [1]. The AutoAnalyzer is an early example of an automated chemistry analyzer using a special flow technique named "continuous flow analysis (CFA)", invented in 1957 by ...
