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 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

Platelet Reaction to Adenosine Diphosphate in vivo

Nature, 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 ...

Poly(adenosine diphosphate ribose)

1982
Publisher Summary This chapter discusses the higher-order structure of poly(adenosine diphosphate ribose) [poly(ADPR)], poly(ADPR) polymerase purification and its properties, and molecular mechanisms of histone- and elongation-factor (EF-2)-ADP-ribosylation.

Adenosine Diphosphate-Degrading Activity in Placenta

Clinical Science, 1983
1. The degradation of ADP by the placenta and umbilical artery was investigated. 2. Supernatants from incubations of finely chopped placental and umbilical arterial tissue were incubated with [14C]ADP for various durations from 0 to 30 min. 3.

Net adenosine diphosphate accumulation in mitochondria

Archives of Biochemistry and Biophysics, 1977
Abstract In addition to the adenine nucleotide exchange translocator, corn mitochondria possess a transport mechanism for the net accumulation of [3H]ADP. The accumulation is energy linked and requires the presence of phosphate and Mg2+. Inhibition of the adenine nucleotide exchange translocator with carboxyatractyloside does not block ADP ...

Selected cardiovascular effects of adenosine diphosphate

American Heart Journal, 1970
Abstract Six intact dogs were studied before, during, and after an 8 minute infusion of ADP, 0.4 mg./min./Kg. There was a significant decrease in aortic pressure, systemic vascular resistance and platelets, and an increase in cardiac output, central blood volume, stroke volume, heart rate, and pulmonary artery pressure.
