Adenosine monophosphate formula

Most flavoproteins, however, do not contain the mononucleotide, but rather flavin-adenine dinucleotide, abbreviated FAD. As in the pyridine nucleotides, adenosine monophosphate and riboflavin phosphate are joined by a pyrophosphate bond. The formula is shown below. 

As another example, cyclic adenosine-3, 5 -monophosphate (formula is in Chapt. XVII-6), which activates phosphorylase, arises from ATP by intramolecular transfer onto the 3 -hydroxyl group, with pyrophosphate elimination.

Nucleoside monophosphates can be further phosphorylated to form nucleoside diphosphates and nucleoside triphosphates. Shovm in Figure 20.4 is a structural formula for adenosine 5 -triphosphate (ATP). 

A nucleotide is a nucleoside in which a molecule of phosphoric acid is esterified with a free hydroxyl of the monosaccharide, most commonly either the 3 -hydroxyl or the 5 -hydroxyl. A nucleotide is named by giving the name of the parent nucleoside followed by the word monophosphate. The position of the phosphoric ester is specified by the number of the carbon to which it is bonded. Figure 28.3 shows a structural formula of adenosine 5 -monophosphate, AMP. Monophosphoric esters are diprotic acids with values of approximately 1 and 6. Therefore, at pH 7, the two hydrogens of a phosphoric monoester are fully ionized, giving a nucleotide a charge of -2. 

Figure 5.4 Structural formulae of thiamin phosphate esters. At present, five natural thiamin phosphate derivatives have been described thiamin monophosphate (ThMP) thiamin diphopshate (ThDP) thiamin triphosphate (ThTP) adenosine thiamin diphosphate (AThDP) and adenosine thiamin triphosphate (AThTP). Catalytic intermediates, such as for instance a-hydroxyethyl thiamine diphosphate formed by the action of yeast pyruvate decarboxylase (EC 4.1.1.1), are not considered here.
