A student studies a diagram of the adenosine molecule in a biology textbook.

Definition

1. Noun:
   • (Biochemistry) A nucleoside that is a structural component of nucleic acids: Adenosine is a fundamental building block present in all living cells. It exists in combined forms as a constituent of crucial biological molecules like DNA, RNA, ADP, ATP, and AMP.

Usage Examples

• Noun:
  • Adenosine is essential for cellular energy transfer.
  • The molecule ATP contains adenosine.
  • Researchers studied the role of adenosine in sleep regulation.

Advanced Usage

• "Adenosine receptor": A type of protein on cell surfaces that adenosine binds to, triggering various physiological responses.

  • Caffeine works by blocking adenosine receptors in the brain.

• "Adenosine deaminase": An enzyme that breaks down adenosine.

  • A deficiency in adenosine deaminase can cause severe immune system disorders.

Variants and Related Words

• Adenosine monophosphate (AMP) (n): A nucleotide derived from adenosine, involved in cellular metabolism.
• Adenosine diphosphate (ADP) (n): A nucleotide important in energy transfer within cells.
• Adenosine triphosphate (ATP) (n): The primary energy currency of the cell.
• Deoxyadenosine (n): The form of adenosine found in DNA.

Synonyms

• Nucleoside (a broader category to which adenosine belongs).

Related Phrases

• Adenosine signaling: Refers to the processes by which adenosine influences cellular activity.
  • Adenosine signaling helps regulate blood flow to tissues.
