Biochem/physiol Actions

Linoleamide is an endogenous lipid, that stimulates sleep in cats, rats and humans.
Linoleamide is an endogenous primary fatty acid amide (PFAM) signaling lipid that modulates intracellular Ca2+ homeostasis. It has been shown to inhibit of SPCA2, a Golgi secretory pathway Ca(2+)-ATPase that transports ions of Ca2+ and Mn2+ and also to inhibit SPCA1a and the Ca2+-ATPase activity of three sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA) pump isoforms. It is thought to be involved in a variety of biological activities including regulation of sleep.

Primary fatty acid amides (PFAM) are important signaling molecules in the mammalian nervous system, binding to many drug receptors and demonstrating control over sleep, locomotion, angiogenesis, and many other processes. Oleamide is the best-studied of the primary fatty acid amides

SERCA maintains intracellular Ca2+ homeostasis by sequestering cytosolic Ca2+ into SR/ER stores. Two primary fatty acid amides (PFAAs), oleamide (18:19-cis) and linoleamide (18:29,12-cis), induce an increase in intracellular Ca2+ levels, which might be caused by their inhibition of SERCA. Three
