Nucleic acid Nucleic acid Nucleic acids are the biopolymers, or small biomolecules, essential to all known forms of life. The term "nucleic acid" is the overall name for DNA and RNA. They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base. If the sugar is a compound ribose, the polymer is RNA (ribonucleic acid); if the sugar is derived from ribose as deoxyribose, the polymer is DNA (deoxyribonucleic acid). Nucleic acids are the most important of all biomolecules. They are found in abundance in all living things, where they
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
