WebT1AM upregulate members of the PAR (Proline and Acidic amino acid Rich), a subfamily of transcription factors involved in the circadian transcription of genes encoding acyl-CoA thioesterases, leading to a cyclic release of fatty acids from thioesters.Produced fatty acids then act as ligands for PPAR[alpha] (Peroxisome Proliferator-Activated Receptors [alpha]), … WebJun 21, 2015 · As a result the thioester carbonyl is not as stabilized by resonance as the ester carbonyl. Said differently, the thioester carbonyl is more reactive (lower activation energy to react) than the ester carbonyl. The thioester motif provides nature with a more reactive carbonyl. This way nature doesn't have to spend as much energy to bring about ...
