Abstract:
Butyrate, a main product of gut microbial fermentation, has been recognized as an important mediator of gut microbiota regulation in whole body energy homeostasis. However, the mechanisms of butyrate metabolic control remain unclear. This review summarizes studies that directly examined the effects of butyrate on metabolic health. The effects of butyrate on metabolic functions, including thermogenesis, lipid and glucose metabolism, appetite, inflammation, and influence on gut microbiota, are described. The effects of butyrate on cellular systems via G protein-coupled receptors (GPRs), as a histone deacetylase inhibitor, and as a substrate that is metabolized intercellularly, are also discussed. Hopefully, a better understanding of butyrate metabolic regulation may provide new perspectives for the nutritional prevention and treatment of metabolic diseases.

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
