Biochem/physiol Actions

beta-Aminoisobutyric acid (BAIBA) is a metabolic biomarker for body exercise induced white fat burning. BAIBA levels rise during exercise and are inversely associated with metabolic risk factors. Specifically, BAIBA levels were inversely correlated with fasting blood sugar levels, insulin, triglycerides, and total cholesterol. The findings suggest that BAIBA may contribute to exercise-induced protection from metabolic diseases.
