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

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 ...

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.

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.

Magnesium, Adenosine Diphosphate and Blood Platelets

Nature, 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

Poly(adenosine diphosphate ribose)

1973
Publisher Summary This chapter discusses that incorporation of radioactivity of (adenine- 14 C) ATP into the acid insoluble material in a nuclear preparation from hen liver is enhanced at least 1000-fold by the presence of NMN. It is confirmed that this stimulation: using a nuclear preparation from rat liver.

Adenosine Diphosphate Glucose and Glucoside Biosynthesis

Nature, 1962
URIDINE diphosphate glucose (UDPG) has been found to act as glucose donor in a number of enzymatic reactions, such as glucoside formation in plants1 and in locust2, sucrose and starch synthesis in plants3,4 and glycogen formation in mammals5.

Adenosine Diphosphate, Adenosine Triphosphate

1955
The increasing importance for animals and bacteria of adenosine diphosphate (ADP) and adenosine triphosphate (ATP) in energy-transfer mechanisms involving such widely diverse processes as muscular contraction, nerve conduction, fire fly luminescence, coenzyme syntheses, tumor growth, polysaccharide synthesis and many other key reactions (McElroy and ...

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 adenosine 5'-diphosphate ribosylation of poly(adenosine diphosphate ribose).

Biochemistry, 1986
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.
