two equations were derived from the multiple regression analysis accounting for the postprandial time course of changes in iri and irg levels with only 5 amino acid concentrations : ( 1 ) ( delta iri ) = 0.37 ( delta leu ) -0.45 ( delta his ) , and ( 2 ) ( delta irg ) = 0.55 ( delta orn ) + 0.37 ( delta gly ) -0.69 ( delta ser ) .
