Palmitate
Description
Palmitate is a term for the salts and esters of palmitic acid (CH3(CH2)14COOH). Palmitic acid is the first fatty acid produced during fatty acid synthesis and the precursor to longer fatty acids. Palmitate negatively feeds back on acetyl-CoA carboxylase (ACC), which is responsible for converting acetyl-CoA to malonyl-CoA, which in turn is used to add to the growing acyl chain, thus preventing further palmitate generation. In order to dissolve the water-insoluble sodium palmitate, BSA is needed to form the water-soluble compound called palmitate:BSA.
