Alkamides: a critical reconsideration of a multifunctional class of unsaturated fatty acid amides
TL;DR: Alkamides are natural products formed by connecting straight-chain, mostly unsaturated, aliphatic acids with various amines by an amide linkage as discussed by the authors and are known from eight plant families consisting of various combinations of 200 acids with 23 amines.
