Description

Oleoylethanolamide (OEA or NOE) is an N-acylethanolamine. N-Acylethanolamines (NAEs) constitute a class of lipid compounds naturally present in both animal and plant membranes as constituents of the membrane-bound phospholipid, N-acylphosphatidylethanolamine (NAPE). NAPE is composed of a third fatty acid moiety linked to the amino head group of the commonly occurring membrane phospholipid, phosphatidylethanolamine. NAEs are released from NAPE by phospholipase D-type hydrolases in response to a variety of stimuli. Transient NAE release and accumulation have been attributed to a variety of biological activities, including neurotransmission, membrane protection, and immunomodulation in animals. Oleoylethanolamide is an inhibitor of the sphingolipid signalling pathway, via specific ceramidase inhibition (ceramidase converts ceramide to sphingosine). Oleoylethanolamide blocks the effects of TNF and arachidonic acid on intracellular Ca concentration (PMID: 12692337 , 12056855 , 12560208 , 11997249 ). Oleoylethanolamide is related to the endocannabinoid anandamide. Endocannabinoids signal through cannabinoid receptors (also stimulated by the active ingredient of cannabis) but although related in structure, synthesis, and degradation to anandamide, OEA cannot be considered an endocannabinoid as it does not activate the cannabinoid receptors. Most of the reported responses to OEA can be attributed to the activation of peroxisome proliferator-activated receptor-alpha (PPAR-alpha). Administration of OEA inhibits body weight gain in rats. In adipocytes and hepatocytes, OEA inhibits mitogenic and metabolic signalling by the insulin receptor and produces glucose intolerance. It also inhibits gastric emptying, which might act together with the sensory neuronal signals to achieve satiety. OEA is permanently elevated in diabetic obese patients. OEA also reduces visceral and inflammatory responses through a PPAR-alpha-activation independent mechanism (PMID: 17449181 ). OEA is an antagonist of TRVP1 (the transient receptor potential vanilloid type 1 receptor). Overall, OEA has beneficial effects on health by inducing food intake control, lipid beta-oxidation, body weight loss and analgesic effects (PMID: 18704536 ).

Enzymes

Enzyme Details

1. Neutral ceramidase

General function:: Involved in ceramidase activity
Specific function:: Hydrolyzes the sphingolipid ceramide into sphingosine and free fatty acid at an optimal pH of 6.5-8.5. Acts as a key regulator of sphingolipid signaling metabolites by generating sphingosine at the cell surface. Acts as a repressor of apoptosis both by reducing C16-ceramide, thereby preventing ceramide-induced apoptosis, and generating sphingosine, a precursor of the antiapoptotic factor sphingosine 1-phosphate. Probably involved in the digestion of dietary sphingolipids in intestine by acting as a key enzyme for the catabolism of dietary sphingolipids and regulating the levels of bioactive sphingolipid metabolites in the intestinal tract.
Gene Name:: ASAH2
Uniprot ID:: Q9NR71
Molecular weight:: 19024.55
