in order to quantify adenosine production from the transmethylation pathway [ s-adenosylmethionine ( adomet ) -- -- s-adenosylhomocysteine ( adohcy ) in equilibrium adenosine + l-homocysteine ] in the isolated guinea-pig heart under basal conditions ( normoxic perfusion with 95 % o2 ) and during elevated adenosine production ( hypoxic perfusion with 30 % o2 ) , two methods were used .
C0036002
s-adenosylmethionine
C0001443
adenosine
