Fig. 2From: Novel metabolic and physiological functions of branched chain amino acids: a reviewIsoleucine up-regulates intestinal and muscular transporters. GLUT1 and GLUT4 are vital glucose transporters in muscle. SGLT1 and GLUT2 are important glucose transporters in the small intestine. Isoleucine could potentially increase muscle growth and intestinal development and health by up-regulating the protein expression of GLUT1 and GLUT4 in muscle and enhancing the expression of SGLT1 and GLUT2 in the small intestineBack to article page
