Palmitoleoylethanolamde
Palmitoleoylethanolamde (POEA), belongs to the class of organic compounds known as N-acylethanolamines. N-Acylethanolamines are compounds containing an N-acyethanolamine moiety, which is characterized by an acyl group is linked to the nitrogen atom of ethanolamine. Thus, palmitoleoylethanolamde is considered to be a fatty amide lipid molecule. Palmitoleoylethanolamde is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. During abstinence, young adults with a history of alcohol binge drinking had elevated plasma levels of monounsaturated and polyunsaturatedacylethanolamides, specifically oleoylethanolamide (OEA), palmitoleoylethanolamide (POEA), arachidonoylethanolamide (AEA), and dihomo-gamma-linolenoylethanolamide (DGLEA). Changes in these lipids positively correlated with mRNA upregulation of inflammatory markers in peripheral blood mononuclear cells (PBMCs), such as toll-like receptors (TLR4), pro-inflammatory cytokines/chemokines, and cyclooxygenase-2 (PMID: 29178411). Palmitoylethanolamide (PEA) is an endogenous fatty acid amide. PEA has been shown to have anti-inflammatory[2] and anti-nociceptive properties.

N-Lauroyl Proline
N-lauroyl proline belongs to the class of compounds known as N-acylamides. These are molecules characterized by a fatty acyl group linked to a primary amine by an amide bond. More specifically, it is a Lauric acid amide of Proline. It is believed that there are more than 800 types of N-acylamides in the human body. N-acylamides fall into several categories: amino acid conjugates (e.g., those acyl amides conjugated with amino acids), neurotransmitter conjugates (e.g., those acylamides conjugated with neurotransmitters), ethanolamine conjugates (e.g., those acylamides conjugated to ethanolamine), and taurine conjugates (e.g., those acyamides conjugated to taurine). N-Lauroyl Proline is an amino acid conjugate. N-acylamides can be classified into 9 different categories depending on the size of their acyl-group: 1) short-chain N-acylamides; 2) medium-chain N-acylamides; 3) long-chain N-acylamides; and 4) very long-chain N-acylamides; 5) hydroxy N-acylamides; 6) branched chain N-acylamides; 7) unsaturated N-acylamides; 8) dicarboxylic N-acylamides and 9) miscellaneous N-acylamides. N-Lauroyl Proline is therefore classified as a long chain N-acylamide. N-acyl amides have a variety of signaling functions in physiology, including in cardiovascular activity, metabolic homeostasis, memory, cognition, pain, motor control and others (PMID: 15655504). N-acyl amides have also been shown to play a role in cell migration, inflammation and certain pathological conditions such as diabetes, cancer, neurodegenerative disease, and obesity (PMID: 23144998; PMID: 25136293; PMID: 28854168).N-acyl amides can be synthesized both endogenously and by gut microbiota (PMID: 28854168). N-acylamides can be biosynthesized via different routes, depending on the parent amine group. N-acyl ethanolamines (NAEs) are formed via the hydrolysis of an unusual phospholipid precursor, N-acyl-phosphatidylethanolamine (NAPE), by a specific phospholipase D. N-acyl amino acids are synthesized via a circulating peptidase M20 domain containing 1 (PM20D1), which can catalyze the bidirectional the condensation and hydrolysis of a variety of N-acyl amino acids. The degradation of N-acylamides is largely mediated by an enzyme called fatty acid amide hydrolase (FAAH), which catalyzes the hydrolysis of N-acylamides into fatty acids and the biogenic amines. Many N-acylamides are involved in lipid signaling system through interactions with transient receptor potential channels (TRP). TRP channel proteins interact with N-acyl amides such as N-arachidonoyl ethanolamide (Anandamide), N-arachidonoyl dopamine and others in an opportunistic fashion (PMID: 23178153). This signaling system has been shown to play a role in the physiological processes involved in inflammation (PMID: 25136293). Other N-acyl amides, including N-oleoyl-glutamine, have also been characterized as TRP channel antagonists (PMID: 29967167). N-acylamides have also been shown to have G-protein-coupled receptors (GPCRs) binding activity (PMID: 28854168). The study of N-acylamides is an active area of research and it is likely that many novel N-acylamides will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered for these molecules.
