Nucleosides and nucleotides: natural bioactive substances in milk and colostrum.
Nucleotides, nucleosides and nucleobases belong to the non-protein-nitrogen (NPN) fraction of milk. The largest amounts of ribonucleosides and ribonucleotides--ribose forms only were considered in this review--were measured directly after parturition in bovine milk and other ruminants as well as in the milk of humans. Generally, concentrations of most of the nucleos(t)ides tend to decrease grad...

متن کاملPulmonary biosynthesis and metabolism of prostaglandins and related substances.
On passage through the lung vascular bed, prostaglandins are removed from the circulation by a transport carrier and subsequently inactivated by intracellular enzymes. However, PGI2 is not inactivated by the lung in vivo. Although PGI2 is an excellent substrate for the intracellular enzymes in vitro, PGI2 is not a substrate for the carrier system. Thus, the transport carrier determines which ci...
