ATP


ATP

A0505400 (ā′tē′pē′)n. A nucleotide, C10H16N5O13P3, that is composed of adenosine and three phosphate groups and releases energy when hydrolyzed to ADP. It is present in all cells, where it is used to store and transport energy needed for biochemical reactions.
[a(denosine) t(ri)p(hosphate).]

ATP

n (Biochemistry) adenosine triphosphate; a nucleotide found in the mitochondria of all plant and animal cells. It is the major source of energy for cellular reactions, this energy being released during its conversion to ADP. Formula: C10H16N5O13P3. Also called: ATPase

ATP

abbreviation for 1. (Aeronautics) advanced turboprop 2. (Tennis) Association of Tennis Professionals 3. (Railways) automatic train protection: a safety system which automatically prevents a train from passing through a stop signal

ATP

adenosine triphosphate: a nucleotide that is the primary source of energy in all living cells because of its function in donating a phosphate group during biochemical activities; composed of adenosine, ribose, and three phosphate groups and formed by enzymatic reaction from adenosine diphosphate and an orthophosphate. Compare ADP. [1940–45]

ATP

(ā′tē′pē′) Short for adenosine triphosphate. An organic compound, C10H16N5O13P3, that is composed of adenosine and three phosphate groups. It serves as a source of energy for many metabolic processes. ATP releases energy when it is broken down into ADP by hydrolysis during cell metabolism.

ATP


adenosine

 [ah-den´o-sēn] 1. a nucleoside composed of the pentose sugar d-ribose and adenine. It is a structural subunit of ribonucleic acid (RNA). Adenosine nucleotides are involved in the energy metabolism of all cells. Adenosine can be linked to a chain of one, two, or three phosphate groups to form adenosine monophosphate (AMP), adenosine diphosphate (ADP), or adenosine triphosphate (ATP). The bond between the phosphate groups in ADP or the two bonds between phosphate groups in ATP are called high-energy bonds, because hydrolysis of a high-energy bond provides a large amount of free energy that can be used to drive other processes that would not otherwise occur. The energy that is derived from the breakdown of carbohydrates, fats, or proteins is used to synthesize ATP. The energy stored in ATP is then used directly or indirectly to drive all other cellular processes that require energy, of which there are four major types: (1) the transport of molecules and ions across cell membranes against concentration gradients, which maintains the internal environment of the cell and produces the membrane potential for the conduction of nerve impulses; (2) the contraction of muscle fibers and other fibers producing the motion of cells; (3) the synthesis of chemical compounds; (4) the synthesis of other high-energy compounds.Adenosine. 2. a preparation of adenosine, which acts as a cardiac depressant of automaticity in the sinus node and conduction in the atrioventricular node and as a vasodilator. It is used as an antiarrhythmic and is also used to cause coronary vasodilation during myocardial perfusion imaging in patients who cannot exercise adequately to perform an exercise stress test, administered intravenously.cyclic adenosine monophosphate a cyclic nucleotide, adenosine 3′,5′-cyclic monophosphate, involved in the action of many hormones, including catecholamines, ACTH, and vasopressin. The hormone binds to a specific receptor on the cell membrane of target cells. This activates an enzyme, adenylate cyclase, which produces cyclic AMP from ATP. Cyclic AMP acts as a second messenger activating other enzymes within the cell. Abbreviated 3′,5′-AMP, cAMP, and cyclic AMP.adenosine diphosphate (ADP) a nucleotide, adenosine 5′-pyrophosphate, produced by the hydrolysis of adenosine triphosphate (ATP). It is then converted back to ATP by the metabolic processes oxidative phosphorylation, glycolysis, and the cycle" >tricarboxylic acid cycle.adenosine monophosphate (AMP) a nucleotide, adenosine 5′-phosphate, involved in energy metabolism and nucleotide synthesis. Called also adenylic acid.adenosine triphosphatase (ATPase) a term used to refer to the enzymatic activity of certain intercellular processes that split ATP to form ADP and inorganic phosphate, when the energy released is not used for the synthesis of chemical compounds. Examples are the splitting of ATP in muscle contraction and the transport of ions across cell membranes.adenosine triphosphate (ATP) a nucleotide, adenosine 5′-triphosphate, occurring in all cells, where it stores energy in the form of high-energy phosphate bonds. Free energy is supplied to drive metabolic reactions, to transport molecules against concentration gradients (active transport), and to produce mechanical motion (contraction of myofibrils and microtubules), when ATP is hydrolyzed to ADP and inorganic phosphate or to AMP and inorganic pyrophosphate. ATP is also used to produce high-energy phosphorylated intermediary metabolites, such as glucose 6-phosphate.

ATP (adenosine triphosphate)

a molecule consisting of ADENINE and ribose sugar on to which are attached three phosphate groups, two being joined by high-energy bonds (see Fig. 55 ). HYDROLYSIS of these special bonds results in the release of energy. ATP molecules are formed in two main processes, both involving the addition of inorganic phosphate to ADP via a high energy bond:

ATP can be formed during CELLULAR RESPIRATION, either in the general cytoplasm during GLYCOLYSIS or in the MITOCHONDRIA via the KREBS CYCLE and the ELECTRON TRANSPORT SYSTEM if oxygen is present. ATP is also formed during photosynthesis in the CHLOROPLASTS of green plants, again using an electron transport system. ATP molecules act therefore as short-term ‘biological batteries’, retaining energy until required for such processes as active transport, synthesis of new materials, nerve transmission, and muscle contraction. An active cell requires more than two million molecules of ATP per second to drive its biochemical machinery.

ATP

Abbreviation for adenosine 5'-triphosphate.

See: Arbitrage Trading Program

Arbitrage Trading Program

A trading strategy taking a long or short position on a stock or commodity and taking the opposite position on a futures contract. This strategy often makes use of a computer program because the transactions involved can become complex and occur in rapid succession. A trader using an arbitrage trading program usually closes the positions toward the end of the futures contract when the prices of the contract and the underlying are approximately equal. This strategy is often used in trading whole baskets of stocks.
