Definitions

1. A six-membered heterocyclic amine ring containing one nitrogen atom, found in many chemical compounds and alkaloids

Etymology: Pepper gave this compound its name. Black pepper's pungent alkaloid is piperine, and when chemists broke it down, they found a nitrogen-containing ring structure and named it after its source. The root "piper" is Latin for pepper, which passed through Greek "peperi" from Sanskrit "pippali." The ending "-idine" was borrowed from pyridine, a related base first obtained from heated bone material. Its name comes from Greek "pyr," meaning fire. Chemists reused that pattern so the new compound's name would signal its chemical family. The shorter form "piperid" drops the final syllable.
