Nucleic acid notation Nucleic acid notation The nucleic acid notation currently in use was first formalized by the International Union of Pure and Applied Chemistry (IUPAC) in 1970. This universally accepted notation uses the Roman characters G, C, A, and T, to represent the four nucleotides commonly found in deoxyribonucleic acids (DNA). Given the rapidly expanding role for genetic sequencing, synthesis, and analysis in biology, researchers have been compelled to develop alternate notations to further support the analysis and manipulation of genetic data. These notations generally exploit size, shape, and symmetry to accomplish these objectives. Degenerate base symbols in biochemistry are an IUPAC
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
