  1. (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
    • example: Caffeine is a purinergic antagonist that competitively inhibits adenosine at the sites of P1 receptors.
    • domain: biochemistry
    • lexical domain: Substances - nouns denoting substances
    • more generic word: nucleoside = a glycoside formed by partial hydrolysis of a nucleic acid

Alternative definition of the noun adenosine

noun

  1. [context: biochemistry, genetics, uncountable] A nucleoside derived from adenine and ribose, found in striated muscle tissue.
  2. [context: countable, chemistry] An instance of adenosine.

Explanation

  1. Adenosine is a purine nucleoside composed of a molecule of adenine attached to a ribose sugar molecule moiety via a β-N₉-glycosidic bond.
    • also known as Adenine nucleoside, Adenine riboside, Adenocard, Adenocor, Adenoscan, Adenosin, Boniton, Myocol, Nucleocardyl, Sandesin
  2. adenosine a.k.a. Adenosine phosphosulfate: 5'-Adenylic acid, monoanhydride with sulfuric acid. The initial compound formed by the action of ATP sulfurylase on sulfate ions after sulfate uptake. Synonyms: adenosine sulfatophosphate; APS.
  3. Adenosine: A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter.
