adenine

“She had used the base pairs of the DNA --- combinations of pairs of four nucleotides called adenine, guanine, cytosine, and thy mine -- to encode her message.”

“The riboswitch Block's team studied grabbed onto a molecule called adenine, the nucleic acid dubbed "A.”

Biosingularity

“This work, carried out between 1882 and 1906 showed that various substances, little known at that time, such as adenine, xanthine, in vegetable substances, caffeine and, in animal excrete, uric acid and guanine, all belonged to one homogeneous family and could be derived from one another and that they corresponded to different hydroxyl and amino derivatives of the same fundamental system formed by a bicyclic nitrogenous structure into which the characteristic urea group entered.”

Emil Fischer - Biography

“The genetic code refers to the sequence of nucleotides (such as adenine, thymine, guanine and cytosine, or A, C, T and G) that serve as the instructions for making amino acids, the building blocks of life.”

Scientific American

“The researchers detected hydrogen cyanide molecules in disks circling 30 percent of the the sun-like stars, may drive a higher production of the hydrogen cyanide Prebiotic molecules, such as adenine, are thought to have rained down to our young planet via meteorites that crashed on the surface.”

“Harden and Young also demonstrated that the process stops before all sugar (glucose) has been used up, but it starts again on addition of inorganic phosphate, and they suggested that hexose phosphates are formed in the early steps of fermentation. von Euler had done important work on the structure of co-zymase, shown to be nicotinamide adenine dinucleotide (NAD, earlier called DPN).”
