The pyrophosphorylysis of adenosine diphosphate glucose and adenosine diphosphate mannose

Biochimica et Biophysica Acta (BBA) - Specialized Section on Enzymological Subjects, 1964
Abstract 1. 1. The biosynthesis of adenosine diphosphate glucose and adenosine diphosphate mannose from adenosine triphosphate and respectively glucose 1-phosphate and mannose 1-phosphate has been observed in extracts from mammalian tissues. The reaction is reversible in the presence of the nucleoside diphosphate sugar and pyrophosphate. 2. 2.

Platelet Reaction to Adenosine Diphosphate in vivo [PDF]

open access: possibleNature, 1965
ADENOSINE diphosphate (ADP) causes agglutination of human1–3, cat4 and rabbit3,5 platelets in vitro and has also been shown to produce a rapid though transient fall in the number of circulating platelets when injected intravascularly4–6. Born and Cross4 postulated that the intravenous injection of the nucleotide led to a drop in the platelet count ...

Platelet Incorporation of Labelled Adenosine and Adenosine Diphosphate

Thrombosis and Haemostasis, 1969
SummaryAfter incubation of platelet-rich plasma with labelled adenosine or ADP, platelet incorporation of radioactivity was assessed. Platelets were rapidly separated for counting by filtration through cellulose acetate Millipore. Inulin-H3 served as a plasma marker, and triple isotope techniques permitted simultaneous assessment of the behavior of the

THE SYNTHESIS AND PROPERTIES OF ADENOSINE-2′ DIPHOSPHATE AND ADENOSINE-3′ DIPHOSPHATE

Canadian Journal of Biochemistry, 1967
Adenosine-2′ diphosphate (A2'DP) and adenosine-3′ diphosphate (A3′DP) have been prepared by reaction between the corresponding mononucleotides with phosphoramidic acid in formamide. The products were isolated by ion-exchange chromatography on DEAE-cellulose and characterized by enzymic and chemical methods. A major side reaction in the synthesis is the

Nonenzymic ADP-ribosylation of poly(adenosine diphosphate ribose)

Biochemistry, 1985
Poly(adenosine 5'-diphosphate ribose) [poly(ADP-ribose]) is spontaneously ADP-ribosylated when it is incubated with nicotinamide adenine dinucleotide, especially in 0.5 M NaCl and at an alkaline pH. The ADP-ribose residues are monomeric and are attached to the middle of polymer chains.

Magnesium, Adenosine Diphosphate and Blood Platelets [PDF]

open access: possibleNature, 1966
RECENTLY we reported1 a relative plasma magnesium deficiency in a group of forty male patients with acute myocardial infarction (mean of 2.3 mg per 100 ml.) compared with thirty-six normal healthy males (mean of 2.6 mg per 100 ml.) in the same age group. In addition it was shown that magnesium added to fresh whole blood delays the clumping of platelets
