ADN
ADN or Adenine Dinucleotide is a nucleotide that is found in the DNA and RNA of all living organisms. It is composed of two parts: the sugar ribose and the nitrogenous base adenine. The term "ADN" is derived from the French term "Acide Désoxyribonucléique", which translates to "Deoxyribonucleic Acid" in English.
Etymology[edit | edit source]
The term "ADN" is an acronym for "Acide Désoxyribonucléique", which is French for "Deoxyribonucleic Acid". The term "Deoxyribonucleic Acid" is derived from the fact that the sugar component of the molecule, deoxyribose, is a type of sugar that lacks one oxygen atom compared to regular ribose. The term "Acid" refers to the fact that DNA has acidic properties.
Structure[edit | edit source]
ADN is composed of two main parts: a sugar molecule called ribose and a nitrogenous base called adenine. The ribose molecule is a pentose sugar, meaning it has five carbon atoms. The adenine molecule is a purine base, which means it is composed of a six-membered and a five-membered nitrogen-containing ring fused to each other.
Function[edit | edit source]
ADN plays a crucial role in the storage and transmission of genetic information in all living organisms. It is the main component of DNA, which is the genetic material that carries the instructions for the development, functioning, growth, and reproduction of all known organisms and many viruses.
Related Terms[edit | edit source]
- DNA: Deoxyribonucleic Acid, the molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms and many viruses.
- RNA: Ribonucleic Acid, a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes.
- Nucleotide: The basic building block of nucleic acids.
- Adenine: A nucleobase (a purine derivative) with a variety of roles in biochemistry including cellular respiration, in the form of both the energy-rich adenosine triphosphate (ATP) and the cofactors nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD).
- Ribose: A carbohydrate with the formula C5H10O5; specifically, it is a monosaccharide (simple sugar) with linear form H−(C=O)−(CHOH)4−H, which has all the hydroxyl groups on the same side in the Fischer projection.
