	Adenosine triphosphate - Wikipedia, the free encyclopedia
		Adenosine triphosphate (ATP) is the nucleotide known in biochemistry as the "molecular currency" of intracellular energy transfer; that is, ATP is able to store and transport chemical energy within cells.
		Also, the hydrolysis yields free inorganic phosphate and adenosine diphosphate, which can be broken down further to another phosphate ion and adenosine monophosphate.
		ATP can also be broken down to adenosine monophosphate directly, with the formation of pyrophosphate.

		Adenosine: A compound derived from nucleic acid, composed of adenine and a sugar, D - ribose.
		Adenosine is the major molecular component of the nucleotides adnosine monophosphate, adenosine diphosphate, and adenosine triphosphate and of the nucleic acids deoxyribonucleic acid and ribonucleic acid.
		Kinds of adenosine phosphate, all of which are inter convertible, are adenosine diphosphate, adenosine monophosphate, and adenosine triphosphate.

	Adenosine
		Adenosine is a naturally occurring nucleoside formed in the body by the enzymatic breakdown of adenosine triphosphate (ATP).
		Adenosine is released from inflamed (infected) tissues or ischemic tissues where there is a decreased blood supply to a particular body organ or part.
		Adenosine is an endogenous nucleoside occurring in all of the cells of the body.

	Olympus MIC-D: Polarized Light Gallery - Adenosine Triphosphate (ATP)
		Adenosine triphosphate, the chemical energy currency of the plant and animal world, is required to for all the processes that keep organisms alive.
		Adenosine triphosphate, a nucleotide, consists of a ribose (five-carbon sugar), a phosphate chain, and a purine base containing carbon and nitrogen atoms (adenine).
		In 1997, the Nobel Prize for Chemistry was shared by Dr. John Walker of Cambridge University, Dr. Paul Boyer from the University of California at Los Angeles (UCLA), and Danish scientist Dr. Jens Skou for their detailed description of the phosphorus cycle featured in the mitochondria of animal cells and the chloroplasts of plant cells.

		Adenosine diphosphate ribose (ADPR) and cyclic adenosine diphosphate ribose (cADPR) are endogenous metabolites of nicotinamide adenine dinucleotide (NAD).
		Adenosine produced in the coronary vascular cells including SMCs has been indicated to contribute to the regulation of coronary blood flow and the protection of the ischemia/reperfusion injury of the heart [33, 34, 53, 54].
		Adenosine then dilates arteries and increases blood flow to the tissue, thereby protecting the tissues or cells from hypoxic and ischemic injury [33, 34].

		Other nucleoside terms may replace "adenosine," "adenylyl," and "Ado" (ref 9).
		Locants and descriptors are custoinarily omitted for the isomers shown, so that the terms may be written as, e.g., phosphoribosyl diphosphate, uridinediphosphoglucose (compound 7).
		Although compound 10 is not an oligophosphoric ester and does not really belong in this table, it is included because it is most often encountered in conjunction with the isomeric compound 9.

	Nucleotide Variations
		The formulas have been abbreviated here and the phosphate is on the other side, but this is intended to show that the adenosine bonded to one phosphate can combine with another phosphate (or phosphoric acid) to form an adenosine that's bonded to two phosphates.
		On the other hand, it is much simpler to write and does show conversion of the adenosine monophosphate plus an inorganic phosphate unit to form adenosine diphosphate.
		The adenosine with two phosphate can in turn combine with a third phosphate group to form adenosine with three phosphates and give off a water molecule, so again, this is a dehydration reaction.
