(biochemistry) a nucleoside that is a structural component of nucleic acids; it is present in all living cells in a combined form as a constituent of DNA and RNA and ADP and ATP and AMP
an enzyme found in mammals that can catalyze the deamination of adenosine into inosine and ammonia; "ADA deficiency can lead to one form of severe combined immunodeficiency disease"; "the gene encoding ADA was one of the earlier human genes to be isolated and cloned for study
Adenosine triphosphate (ATP) is a nucleotide that is of fundamental importance as a carrier of chemical energy in all living organisms ATP can undergo hydrolysis, a reaction triggered by ATPase, which releases a large amount of energy that is used to fuel such biological processes as muscle contraction or the active transport of ions and molecules across cell membranes, or the synthesis of biomolecules
ATP, C10H16N5O13P3, is an organic compound composed of adenine, the sugar ribose, and three phosphate groups It serves as the major energy source within the cell to drive a number of biological processes such as photosynthesis, muscle contraction, and the synthesis of proteins
An organic, phosphate-rich compound important in the transfer of energy in organisms Its central role in living cells makes it an excellent indicator of the presence of living material in water A measure of ATP therefore provides a sensitive and rapid estimate of Biomass ATP is reported in micrograms per liter of the original water sample
