Palmitate is the major component of palm oil, The word is from the French "palmitique", the pith of the palm tree. Palmitate also called n-hexadecanoate whose Chemical Formula is CH3(CH2)14COO−. palmitate is the dissociated and observed form of palmitic acid at physiological pH. Palmitate is the anion of a saturated 16 carbon fatty acid, and the first product of lipogenesis (Fatty Acid Synthesis).
In metabolism, palmitate negatively feeds back on Acetyl-CoA Carboxylase (ACC) which is responsible for converting acetyl-ACP to malonyl-ACP on the growing acyl chain. Thus preventing further palmitate generation.
