Common Name | Palmitic amide |

Description | Palmitic amide is a primary fatty acid amide coming from Palmitic acid (C16:0). Primary fatty acid amides (R-CO-NH2) is a class of compounds that have only recently been isolated and characterized from biological sources. Key questions remain regarding how these lipid amides are produced and degraded in biological systems. (PMID 15282088 ). Fatty acid amides lies in the competition with endocannabinoids for binding to the active site of the enzyme and thus in increasing the concentration of endocannabinoids, by preventing their degradation.It can be used as a marker of disease in subjects, e.g. first-onset, drug-naive patients; the disease may be, for example, schizophrenia, paranoid schizophrenia or an affective disorder.The metabolic network of primary fatty acid amides is more severely altered in affective disorder than in first onset, paranoid schizophrenia. |
