3-Aminoisobutyric acid (or β-aminoisobutyric acid, BAIBA) is a product formed by the catabolism of thymine.

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.^[1] One of the consequences of the BAIBA activity is the increase of the background metabolism of the BAIBA target cells.

It has recently been postulated to play a role in cell metabolism, how body burns fat and regulates insulin, triglycerides, and total cholesterol.^[2]
