n-oleoyl glycine

N-Oleoyl Glycine, a Lipoamino Acid, Stimulates Adipogenesis Associated With Activation of CB1 Receptor and Akt Signaling Pathway in 3T3-L1 Adipocyte

The acyl amides are a family of endogenous lipids that act as potent modulators of pain and inflammation. The best characterized members of this family are the arachidonoyl amides, which includes N-arachidonoyl ethanolamide (AEA; anandamide). N-palmitoyl glycine (PalGly) contains an 18-carbon saturated fatty acid that is amide-linked to glycine and is structurally similar to the phospholipid-derived N-acyl ethanolamines. Endogenously produced in rat skin and spinal cord, PalGly is present in 100-fold greater amounts in skin and 3-fold greater in brain compared to AEA. Injection of 0.43 μg PalGly in rat hindpaw inhibits heat-induced firing of nociceptive neurons in rat dorsal horn. PalGly treatment induces transient calcium influx in native dorsal root ganglion (DRG) cells and in the PTX-sensitive, DRG-like cell line F-11 (EC50 = 5.5 μM).

N-(3-Phenylpropionyl)glycine (Phenylpropionylglycine) is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. Acyl glycines are produced through the action of glycine N-acyltransferase which is an enzyme that catalyzes the chemical reaction:acyl-CoA + glycine < - > CoA + N-acylglycineThe detection of phenylpropionylglycine in urine after an oral load of phenylpropionic acid can be used to diagnose deficiency of medium-chain acyl-CoA dehydrogenase, a frequent and treatable metabolic defect.
