Description
Ractopamine is a potent β-adrenergic receptor (βAR) agonist with Kd value of ~25 nM for pig β1AR and β2AR. Ractopamine is linked to protein metabolism. Ractopamine is structurally similar to the natural catecholamines epinephrine and norepinephrine, and binds with high affinity to βAR in pig adipose and muscle tissue. Ractopamine can be used for researching to increase lean tissue growth and improve production efficiency in pigs
