Identification
Name:Dodecanoate (N-C12:0)
DescriptionDodecanoate (n-c12:0) belongs to the class of Carboxylic Acid Salts. These are ionic derivatives of carboxylic acid. (inferred from compound structure) Dodecanoic acid, also known as lauric acid is a saturated fatty acid with a 12-carbon atom chain, thus falling into the medium chain fatty acids. It is a white, powdery solid with a faint odor of bay oil or soap. (Wikipedia) In plants and bacteria like E. coli, dodecanoate is a by-product in one palmitate biosynthesis pathway. (EcoCyc)
