Wikipedia
Adenine (A, Ade) is a nucleobase (a purine derivative). Its derivatives have 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). It also has functions in protein synthesis and as a chemical component of DNA and RNA. The shape of adenine is complementary to either thymine in DNA or uracil in RNA.
The image right shows pure adenine, as an independent molecule. When connected into DNA, a covalent bond is formed between deoxyribose sugar and the bottom left nitrogen, so removing the hydrogen. The remaining structure is called an adenine residue, as part of a larger molecule. Adenosine is adenine reacted with ribose as used in RNA and ATP; deoxyadenosine adenine attached to deoxyribose, as is used to form DNA.
Adenine, named after the nucleobase adenine, is a scripting language that is cross-platform, which is developed in the context of project Haystack and Project Oxygen of the Massachusetts Institute of Technology (MIT) Computer Science and Artificial Intelligence Laboratory (CSAIL) in collaboration with Nippon Telegraph and Telephone (NTT).
Adenine was developed as the implementation language of the Haystack Semantic Desktop. It is the perhaps the earliest example of a homoiconic general graph (rather than list/tree) programming language.
A substantial characteristic of Adenine is that this language possesses native support for the Resource Description Framework (RDF). The language constructs of Adenine are derived from Python and Lisp.
Adenine is written in RDF and thus also can be represented and written with RDF based syntaxes such as Notation3 (N3). Also, as well as RDF, Adenine can be extended. The data type system corresponds to the data type system from RDF and XML Schema, and can be extended.
