The mammalian sirtuins (Sirt1--Sirt7) participate in a number of cellular and physiological functions such as gene silencing, apoptosis, mitochondrial function, energy homeostasis, and longevity [237].Transgenic mice with overexpression of the sirt1 gene demonstrate decreased lipid-induced inflammation, improved glucose tolerance, and protection from hepatic steatosis when fed a high-fat diet [238]

The acetyl moiety prevents the thiol group from oxidizing before absorption, shields the molecule from -GT-mediated hydrolysis in the intestinal lumen, and increases lipophilicity facilitating passive diffusion across intestinal epithelium and cell membranes
