Definition

1. Noun:
   • A nucleoside component of DNA: "Deoxyadenosine" is a chemical compound that is one of the fundamental building blocks of deoxyribonucleic acid (DNA). It is composed of the nucleobase adenine linked to the sugar deoxyribose.

Usage Examples

• Noun:
  • Deoxyadenosine is one of the four nucleosides found in DNA.
  • The enzyme catalyzes the phosphorylation of deoxyadenosine.
  • A deficiency in the breakdown of deoxyadenosine can lead to certain immune disorders.

Advanced Usage

• "Deoxyadenosine triphosphate (dATP)": This is the activated, triphosphate form of deoxyadenosine, which serves as a direct monomeric precursor for DNA synthesis during replication.
  • DNA polymerase incorporates dATP into the growing DNA strand.

Variants and Related Words

• Deoxyadenylate (n): The nucleotide form of deoxyadenosine (i.e., deoxyadenosine monophosphate, dAMP).
• Adenosine (n): The related nucleoside found in RNA, where the sugar component is ribose instead of deoxyribose.

Synonyms

• dA (abbreviation): A common shorthand notation in biochemistry and genetics.
• 2'-Deoxyadenosine: The full systematic name specifying the position of the deoxy modification on the sugar ring.

Related Phrases and Compounds

• Deoxyadenosine diphosphate (dADP): The diphosphate derivative.
• Deoxyadenosine monophosphate (dAMP): The monophosphate nucleotide.

Noun

1. a nucleoside component of DNA; composed of adenosine and deoxyribose
