Turnover of pancreas phospholipids in rats fed inadequate dietary protein.
Effect of feeding rice diets with and without lysine and threonine supplementation has been studied on phospholipid turnover of rat pancreas and compared to rats fed casein diet at 20% protein level. Rice diet without amino acid supplementation significantly reduced the levels of pancreas PC, PE, PI, PS and Sph and increased that of total cholesterol and TG. Incorporation of palmitate-1-14C, labelled choline, labelled methionine and NaH2(32)PO4 into PC and of palmitate-1-14C into TG was significantly reduced in rats fed unsupplemented rice diet. Incorporation of NaH2(32)PO4 into pancreas PI, DPI, TPI, PA, LPA and into IP, IP2', IP3 and GPI was significantly reduced in rats fed unsupplemented rice diet.
