Additional information


9-dodecenoic acid, methyl ester is a fatty acid methyl ester. Metabolism of fatty acid methyl esters begins with hydrolysis of the ester, resulting in the carboxylic (e.g. fatty) acid and methanol. Methanol is oxidized to formaldehyde, which itself is oxidized to formic acid. Finally, formic acid is metabolized to CO2 and H2O. Fatty acids are an important source of energy and adenosine triphosphate (ATP) for many cellular organisms. Fatty acids undergo β-oxidation, and the products enter physiological pathways like the citric acid cycle, sugar synthesis, and lipid synthesis.

Dermal Absorption

Using the US NIOSH Finite Dose Skin Permeation Calculator, systemic absorption of 9-dodecenoic acid, methyl ester across partially hydrated human skin is predicted to be very low.
