Oleamide is an organic compound with the formula CH3(CH2)7CH=CH(CH2)7CONH2.[3] 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.[4]
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.[4][5]
It has been considered as a treatment for mood and sleep disorders, as well as cannabinoid-regulated depression.[6][7]
In terms of its sleep inducing effects, it is speculated that oleamide interacts with multiple neurotransmitter systems.[8][9] Some in-vitro studies show that cis-oleamide is an agonist for the cannabinoid receptor CB-1 with an affinity around 8 micromolar.[10] 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.[11] At larger doses oleamide can lower the body temperature of mice by about 2 degrees, with the effect lasting about two hours.[9] The mechanism for this remains unknown.[9]
Oleamide has been found to enhance PPARα-dependent increase in doublecortin, a marker of neurogenesis in the hippocampus[12]
Oleamide is rapidly metabolized by fatty acid amide hydrolase (FAAH), the same enzyme that metabolizes anandamide.[13] It has been postulated that some effects of oleamide are caused by increased concentrations of anandamide brought about through the inhibition of FAAH.[9]
It has been claimed that oleamide increases the activity of choline acetyltransferase, an enzyme that is critical in the production of acetylcholine.[14]
Other occurrences
[edit]Oleamide has been found in Ziziphus jujuba, also known as Jujube fruit.[14]
Synthetic oleamide has a variety of industrial uses, including as a lubricant.[15]
Oleamide was found to be leaching out of polypropylene plastics in laboratory experiments, affecting experimental results.[16] Since polypropylene is used in a wide number of food containers such as those for yogurt, the problem is being studied.[17]
Oleamide is "one of the most frequent non-cannabinoid ingredients associated with Spice products."[18] Analysis of 44 products synthetic cannabinoid revealed oleamide in 7 of the products tested.[19]
