Three possible reasons for inhibitory effect of de novo fatty acid synthesis by stearate are as follows: i) Stearate inhibited de novo synthesis of fatty acid by down-regulating the mRNA expression of ACACA and FASN; ii) Long-chain acyl-CoA competed with newly synthesized medium-chain acyl-CoA for the sn-2 and sn-3 positions of the triacylglycerol backbone; iii) long-chain acyl-CoA inhibited de novo synthesis of fatty acid by suppression of acetyl-CoA carboxylase (Hansen and Knudsen.
