| Common Name | Senecioic acid |

| Description | Senecioic acid, also known as 3-methylcrotonate, 3-methylcrotonic acid or 3,3-dimethylacrylic acid, belongs to the class of organic compounds known as methyl-branched fatty acids. These are fatty acids with an acyl chain that has a methyl branch. Usually, they are saturated (however senecioic acid is unsaturated) and contain only one or more methyl group. However, branches other than methyl may be present. Senecioic acid is a methyl-branched fatty acid that has a but-2-enoic acid skeleton bearing a methyl substituent at position 3. Senecioic acid is an unsaturated fatty acid found in the pheromones of mealybug species, the Madeira cockroach and the Southern long-nosed bat. It also appears in the urine of patients with 3-Methylcrotonic aciduria caused by 3-hydroxy-3-methylglutaryl-CoA lyase deficiency (PMID: 6157502 ) And those with 3-Hydroxy-3-methylglutaric aciduria (PMID: 947633 ). The appearance of 3-methylcrotonic acid in urine indicates a blockage in the sixth step of leucine catabolism, which is the cleavage of 3-hydroxy-3-methylglutaryl-CoA to acetoacetic acid and acetyl-CoA. |
