Oleamide is an organic compound with the formula CH3(CH2)7CH=CH(CH2)7CONH2(.[4] It is the amide derived from the fatty acid oleic acid. It is a colorless waxy solid and occurs in nature. Sometimes labeled as a fatty acid primary amide (FAPA), it is biosynthesized from N-oleoylglycine.[5]

Biochemical and medical aspects[edit]

In terms of natural occurrence, oleamide was first detected in human plasma. It was later shown to accumulate in the cerebrospinal fluid during sleep deprivation and induces sleep in animals.[5][6]

It has been considered as a potential treatment for mood and sleep disorders, as well as cannabinoid-regulated depression.[7][8]

In terms of its sleep inducing effects, it is speculated that oleamide interacts with multiple neurotransmitter systems.[9]

Other occurrences[edit]

Synthetic oleamide has a variety of industrial uses including as a slip agent, a lubricant, and a corrosion inhibitor.[10]

Oleamide was found to be leaking out of polypropylene plastics in laboratory experiments, affecting experimental results.[11] Since polypropylene is used in a wide number of food containers such as those for yogurt, the problem is being studied.[12]

Oleamide is "one of the most frequent non-cannabinoid ingredients associated with Spice products."[13] Analysis of 44 products synthetic cannabinoid revealed oleamide in 7 of the products tested.[14]
