A molecule isolated from the cerebrospinal fluid of sleep-deprived cats has been chemically characterized and identified as cis-9,10-octadecenoamide. Other fatty acid primary amides in addition to cis-9,10-octadecenoamide were identified as natural constituents of the cerebrospinal fluid of cat, rat, and human, indicating that these compounds compose a distinct family of brain lipids. Synthetic cis-9,10-octadecenoamide induced physiological sleep when injected into rats. Together, these results… 
The sleep inducing factor oleamide is produced by mouse neuroblastoma cells.
TLDR
It is shown for the first time that oleamide is produced by a neuronal cell type and that its biosynthesis in intact neurons is not likely to occur through the direct condensation of oleic acid and ammonia.
Synthesis and biological evaluation of novel amides of polyunsaturated fatty acids with dopamine.
Identification of an unusual naturally occurring apolar fatty acid amide in mammalian brain and a method for its quantitative determination.
TLDR
Evidence is provided of the occurrence in mouse and bovine brain extracts of a compound characterised by a mass spectrum attributable to a FAA not previously described, namely, the isopropyl-amide of stearic acid (SIPA), which shows surprisingly that SIPA may be found naturally in mammalian biological extracts.

TLDR
The ability of brain tissue to enzymatically synthesize anandamide and the existence of specific receptors for this eicosanoid suggest the presence of an andamide-containing (anandaergic) neurons.

TLDR
This review focuses on one of the steps in peptide biosynthesis, peptide a-amidation, and summarizes information obtained primarily over the past few years, because several previous reviews comprehensively cover earlier work on peptide IY.
