Adenosine is used as an intravenous medication for some cardiac arrhythmias. Adenosyl (abbreviated Ado or 5'-dAdo ) is the chemical group formed by removal of the 5′-hydroxy (OH) group. It is found in adenosylcobalamin (an active form of vitamin B12 [ 1 ] ) and as a radical in the radical SAM enzymes.
Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide.AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine.It is an ester of phosphoric acid and the nucleoside adenosine. [1]
Transgenetically expressed, ADO appears to be dependent on ferredoxin-ferredoxin reductase to deliver reducing equivalents, but the endogenous reducing system is not known. [2] Further, oxygen-independent aldehyde deformylation has also been observed. [6] H 2 O 2 is an inhibitor of cADO, and an ADO-catalase fusion protein exhibits improved ...
Adenosine kinase (AdK; EC 2.7.1.20) is an enzyme that catalyzes the transfer of gamma-phosphate from Adenosine triphosphate to adenosine (Ado) leading to formation of Adenosine monophosphate . In addition to its well-studied role in controlling the cellular concentration of Ado, AdK also plays an important role in the maintenance of methylation ...
The energy used by human cells in an adult requires the hydrolysis of 100 to 150 mol/L of ATP daily, which means a human will typically use their body weight worth of ATP over the course of the day. [30] Each equivalent of ATP is recycled 1000–1500 times during a single day (150 / 0.1 = 1500), [29] at approximately 9×10 20 molecules/s. [29]
S-Adenosyl methionine (SAM), also known under the commercial names of SAMe, SAM-e, or AdoMet, is a common cosubstrate involved in methyl group transfers, transsulfuration, and aminopropylation.

Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. [1] [2] Modern science is typically divided into two or three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the behavioural sciences (e.g., economics, psychology, and sociology ...
