- One of these labels is ethenoadenine, which is obtained by chemical modification of adenine.

- There are two genes in the adenine biosynthetic pathway of yeast (ADE1 and ADE2) that, apart from producing an absolute requirement for adenine when mutant, also produce a change in colony color.

- The HCN pentamer, adenine (a constituent of DNA, RNA and many coenzymes), is one of the most abundant biochemical molecules.
