Uridine Uridine Uridine is a glycosylated pyrimidine-analog containing uracil attached to a ribose ring (or more specifically, a ribofuranose) via a β-N-glycosidic bond. It is one of the five standard nucleosides which make up nucleic acids, the others being adenosine, thymidine, cytidine and guanosine. The five nucleosides are commonly abbreviated to their one-letter codes U, A, T, C and G respectively. However, thymidine is more commonly written as 'dT' ('d' represents 'deoxy') as it contains a 2'-deoxyribofuranose moiety rather than the ribofuranose ring found in uridine. This is because thymidine is found in deoxyribonucleic acid (DNA) and not ribonucleic acid (RNA).
Epoxydocosapentaenoic acid wildly distributed in organs and tissues such as the liver, kidney, heart, lung, pancreas, intestine, blood vessels, blood leukocytes, and brain. These tissues are known to metabolize arachidonic acid to EETs; it has been shown or is presumed that they also metabolize DHA to EPD's. The EDPs are commonly made by the stimulation of specific cell types by the same mechanisms which produce EETs (see Epoxyeicosatrienoic acid). That is, cell stimulation causes DHA to be released from the "sn-2" position of their membrane-bound cellular phospholipid pools through the action of a Phospholipase A2-type enzyme and the subsequent attack of the
