Analytical Chemistry substances separation methodAbstract:Fatty acid synthase（FAS） is the most important enzyme in synthesis fatty in cell. FAS catalyse Ac-CoA and Mal-CoA into long chain fatty acid. To inhibit the activity of FAS, it can block and reduce the access of synthesis fatty acid and in body. At the same time, it also can increase the concentration of Mal-CoA which cause the decrease of appetite. Academe has point out that FAS is both target of treatment of cancer and obesity. But the FAS inhibitor has been discovered is very lack. Cerulenin is toxic. C75 needs very high concentration of periphery dose. EGCG has poor inhibit ability.[著者文摘]
