Etymology: The plural "purines" is simply the form of "purine," a name for a family of nitrogen-rich organic compounds. The word "purine" was borrowed from German "Purin," which was coined in 1884 by the German chemist Emil Fischer, who built the term from "pur-" (from Latin "purus," meaning pure) and the chemical suffix "-in." Fischer chose it because the parent compound could be made from uric acid, a substance that is itself a product of the body's metabolism. Fischer's name was a sort of acknowledgement of his work on the chemistry of the compound family, which had been studied for decades before he gave it a single name. The name stuck in English as well, where the plural refers to the whole class of substances, including adenine and guanine, that make up part of DNA and RNA.
