Adenosine S -phosphate

For example, adenosine-S -phosphate (AMP) becomes attached to a respiratory enzyme, NADH2 dehydrogenase (E) ...

The 5 -adenyhc acid deaminase (22) found in rabbit muscle has been crystallized (23). It converts adenylic acid to inosinic acid and ammonia [Eq. (7)]. The enzyme does not deaminate adenine, adenosine, adenosine diphosphate, adenosine triphosphate, adenosine 2 -phosphate, adenosine S -phosphate, guanosine, or cytosine but does act upon deoxyadenylic acid (24)-... 

If a sugar is esterified with two or more phosphate groups, the compound is termed bisphosphate, trisphosphate etc. (e.g. fructofuranose 1,6-bisphosphate). The term diphosphate denotes an ester with diphosphoric acid, e.g. adenosine S -diphosphate.

These are the energy producers within the cell. They generate energy in the form of Adenosine Tri-Phosphate (ATP). Generally, the more energy a cell needs, the more mitochondria it contains.

The interesting 0-alkyl ferrocenecarbothioates are available from S-methyl ferrocenecarbodithioate. Instead of thioxo- or dithio-carboxylic esters thioacylimidazoles were successfully applied in certain cases, for instance in preparing T- (53) or 3 -0-(fV-acetylthioleucyl)adenosine 5 -phosphate. ... 

Even more pronounced general acid catalysis by nucleoside monophosphates in the hydrolysis of diol epoxides 80 and 81 is observed.90 In Fig. 3 are plots of obsd versus total concentrations of guanosine (G), ribose S -phosphate, 5Ccytosine monophosphate (5 -CMP), 5 -adenosine monophosphate (5 -AMP) and 5Cguanosine... 

Conjugation of 0-, N- and S-contalnlng functional groups with sulfate Is very common In animal systems. Sulfate Is transferred from adenosine 3 -phosphate-5 -sulfatophosphate (PAPS) by a variety of transfer enzymes. The mechanisms for sulfation of xenobiotics (74,75) and the chemistry of sulfate esters and related compounds and the synthesis of these have been reviewed (75-77). Syntheses of 0-, N- and S-sulfate conjugates of xenobiotics may be carried out by the methods described below. 

Structural formula of adenosine triphosphate (ATP) at pH 7.0, The three phosphate groups are identified by Greek letters a, fi, and y. The y- and S-phosphate groups are linked through phosphoanhydride bonds and their hydrolysis yields a large negative AG°, whereas the cr-phosphate linked by a phosphate ester bond has a much lower negative AG°. ... 

Chemicals. Ring-labelled [ H]-octopamine (44 Ci/mmol) and [2,8- H]adenosine S tS -cyclic phosphate (41 Ci/mmol) were purchased from Amersham Corp., Arlington Hts., IL. Xylamine was synthesized by the method of Ransom et al. (14). Chlordimeform (CDM), N-demethylchlordimeform (DCDM), and N,N-bisdemethylchlordimeform (DDCDM) were synthesized as described by Hollingworth (15).
