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][10] Some in-vitro studies show that cis-oleamide is an agnoist for the cannabinoid receptor CB-1 with an affinity around 8 micromolar.[11] However, given oleamide's relatively low affinity for CB-1 and uncertainty about the concentration and biological role of oleamide in-vivo, it has been argued that it is premature to classify oleamide as an endocannabinoid.[12] At larger doses oleamide can lower the body temperature of mice by about 2 degrees, with the effect lasting about two hours.[10] The mechanism for this remains unknown.[10]

Oleamide is rapidly metabolized by fatty acid amide hydrolase (FAAH), the same enzyme that metabolizes anandamide.[10][13] It has been postulated that some effects of oleamide are caused by increased concentrations of anandamide brought about through the inhibition of FAAH.[10]

Other occurrences[edit]

Synthetic oleamide has a variety of industrial uses including as a slip agent, a lubricant, and a corrosion inhibitor.[14]

Oleamide was found to be leaching out of polypropylene plastics in laboratory experiments, affecting experimental results.[15] Since polypropylene is used in a wide number of food containers such as those for yogurt, the problem is being studied.[16]

Oleamide is "one of the most frequent non-cannabinoid ingredients associated with Spice products."[17] Analysis of 44 products synthetic cannabinoid revealed oleamide in 7 of the products tested.[18]
