adenine

 [ad´ĕ-nēn]
a purine base present in nucleoproteins of cells of plants and animals; adenine and guanine are essential components of nucleic acids. The end product of the metabolism of adenine in humans is uric acid. A preparation of adenine is used to improve the preservation of whole blood. Symbol A.
adenine arabinoside (ara-A) vidarabine.

ad·e·nine (A, Ade),

(ad'ĕ-nēn),
One of the two major purines (the other is guanine) found in both RNA and DNA, and also in various free nucleotides of importance to the body (for example, AMP (adenylic acid), ATP, NAD+, NADP+, and FAD); in all these smaller compounds, adenine is condensed with ribose at nitrogen-9, forming adenosine. For structure, see adenylic acid.
Synonym(s): 6-aminopurine

adenine

/ad·e·nine/ (ad´ĕ-nēn) a purine base; in plant and animal cells usually occurring complexed with ribose or deoxyribose to form adenosine and deoxyadenosine, components of nucleic acids, nucleotides, and coenzymes. A preparation is used to improve the preservation of whole blood. Symbol A.
adenine arabinoside  vidarabine.

adenine

(ăd′n-ēn′, -ĭn)
n. Abbr. A
A purine base, C5H5N5, that is the constituent involved in base pairing with thymine in DNA and with uracil in RNA.

adenine

[ad′ənin]
a purine base that is a component of DNA, RNA, adenosine monophosphate (AMP), cyclic AMP, adenosine diphosphate(ADP), and adenosine triphosphate (ATP).

Adenine

One of 2 (the other is thymine) major purine bases (C5H5N5) in nucleic acid. Adenine pairs with a pyrimidine in nucleic acids—with thymine in DNA, or with uracil in RNA; adenine combines with deoxyribose to form deoxyadenosine in DNA and ribose to form adenosine in RNA. Adenine is a major factor in a plethora of biological and molecular reactions.

ad·e·nine

(A, Ade) (ad'ĕ-nēn)
One of the two major purines (the other being guanine) found in both RNA and DNA, and also in various free nucleotides.

adenine

A purine base. One of the four key biochemical units from which genes are formed in DNA and by which the two helical halves of the DNA molecule are linked together. Adenine pairs with thymine in DNA, but in RNA it pairs with uracil.

adenine (A)

one of four types of nitrogenous bases found in DNA, having the double-ring structure of a class known as PURINES (see Fig. 13 ).

Adenine forms part of a DNA unit called a NUCLEOTIDE and always forms COMPLEMENTARY BASE PAIRING with a DNA PYRIMIDINE base called THYMINE (see Fig. 14 ). When pairing with RNA during TRANSCRIPTION, adenine is complementary to URACIL. Adenine also occurs in RNA molecules, ATP, ADP and AMP.

ad·e·nine

(ad'ĕ-nēn)
A purine found in both RNA and DNA, and also in various free nucleotides of importance to the body.

adenine (ad´ənēn),

n a component of the nucleic acids, DNA and RNA, and a constituent of cyclic AMP and the adenosine portion of AMP, ADP, and ATP.

adenine

a purine base present in nucleoproteins of cells of plants and animals. Adenine and guanine are essential components of nucleic acids.

adenine arabinoside
adenine nucleotide translocator
protein in the inner mitochondrial membrane; exchanges ADP produced by reactions in the cytosol for ATP produced in the mitochondrion by oxidative phosphorylation.
