|Section2= |Section3= }} 3-Aminoisobutyric acid (or β-aminoisobutyric acid, 'BAIBA') is a product formed by the catabolism of thymine. It has recently been postulated to play a role in cell metabolism, how body burns fat and regulates insulin, triglycerides, and total cholesterol.〔http://medicalxpress.com/news/2014-01-molecule-benefits.html〕 During exercise, the increase of PGC-1α protein triggers the secretion of BAIBA from exercising muscles to blood (concentration 2 to 3 µM in human serum). When BAIBA reaches the white fat tissue, it activates the expression of thermogenic genes via PPARα receptors, resulting in a browning of white fat cells.〔http://www.cell.com/cell-metabolism/retrieve/pii/S155041311300497X〕 One of the consequences of the BAIBA activity is the increase of the background metabolism of the BAIBA target cells. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「3-Aminoisobutyric acid」の詳細全文を読む スポンサード リンク
