Adenosine 5 -triphosphate high-energy compound

ATP Adenosine triphosphate. Chemical energy generated by substrate oxidations is conserved by formation of high-energy compounds such as adenosine diphosphate (ADP) and adenosine triphosphate (ATP) or compounds containing the thioester bond. 

Ill these simultaneous reactions, die energy released when the complex molecule AB is broken down is immediately used to build a molecule of adenosine triphosphate (ATP) from a molecule of adenosine diphosphate (ADP) and an inorganic phosphate (P,). ATP is a high energy compound. It is called the energy currency of the body because once it is formed, it provides energy that the body can spend later to drive vital reactions in cells (Figure 1). 

When two acid molecules condense by elimination of a molecule of water, the product is called an acid anhydride, as can be seen in Figure 12.60. Acid anhydrides are always very reactive, or high-energy, compounds. When deoxy-adenosine monophosphate forms an anhydride with phosphoric acid, we have deoxyadenosine diphosphate (dADP). Of course, if we add an additional phosphate group, we have deoxyadenosine triphosphate (dATP). 

A compound found in the cells and involved in the storage of energy. It combines with a further phosphate group to form ATP or adenosine triphosphate, which is a high-energy compound that is essential for cell energetics. 

Ligases split C-C, C-O, C-N, C-S, and C-halogen bonds without hydrolysis or oxidation, mostly with the concomitant consumption of high-energy compounds like adenosine triphosphate (ATP) and other nucleoside triphosphates. 

ATP Adenosine triphosphate a high-energy compound produced in photosynthesis and respiration which is used as the main energy currency of cells. 

Minute spheres, rods, or filaments in the cytoplasm. Mitochondria are the sites of numerous biochemical reactions including amino acid and fatty acid catabolism, the oxidative reactions of the KreE)s cycle, respiratory electron transport, and oxidative phosphorylation. As a result of these reactions, mitochondria are the major producers of the high energy compound adenosine triphosphate (ATP) in aerobically grown cells. 

In our cells, the energy released from the oxidation of the food we eat is stored in the form of a high-energy compound called adenosine triphosphate (ATP). The ATP molecule is composed of the base adenine, a ribose sugar, and three phosphate groups. 

Energy obtained from catabolic reactions is stored in adenosine triphosphate (ATP), a high-energy compound that is hydrolyzed when energy is required by anabolic reactions. 

In this connection, the following discussion will be devoted to common biochemical processes connected to energy release and accumulation in adenosine triphosphate (ATP), based on the above suggestion that chemical energy is accumulated in highly active intermediate compounds.
