Adenosine Diphosphate: From 1 Different Sources


Adenosine Triphosphate (atp)

A compound comprising the chemical substances adenine, ribose and phosphates. The chemical bonds of the phosphates contain energy needed for cell METABOLISM that occurs when muscle cells contract. This energy is made available when ATP breaks up to form other chemical groupings – adenosine diphosphate (ADP) and adenosine monophosphate (AMP). The energy needed for recombining AMP and ADP to form ATP is produced by the breakdown of carbohydrates or other constituencies of food.... adenosine triphosphate (atp)

Adenosine Deaminase Deficiency

(ADA deficiency) a genetic disorder affecting about one baby in 25,000 and characterized by a defect in adenosine deaminase (ADA), an enzyme that is involved in purine metabolism. Deficiency of this enzyme results in selective damage to the antibody-producing lymphocytes; this in turn leads to a condition known as *severe combined immune deficiency (SCID), in which the affected baby has no resistance to infection and must be entirely isolated from birth. Such children have only about a 50% chance of surviving for six months. See also gene therapy.... adenosine deaminase deficiency

Adenosine Monophosphate

see AMP.... adenosine monophosphate

Adenosine Triphosphate

see ATP.... adenosine triphosphate
