Popis: We studied the effect of various energetic nutrients on metabolism of L-[U-14C]leucine and [1-14C]glycine in cerebral cortex of rats at different ages. At gestational age, glucose and lactate stimulated protein synthesis from L-[U-14C]leucine and [1-14C]glycine and from L-[U-14C]leucine, respectively; glucose, beta-OH-butyrate and lactate stimulated lipid synthesis from L-[U-14C]leucine. At 10 days of age, glucose, mannose, and fructose stimulated protein synthesis, and glucose and mannose stimulated oxidation to CO2 as well as lipid synthesis from L-[U-14C]leucine. In adult rats, glucose, mannose, and fructose stimulated protein synthesis from L-[U-14C]leucine and [1-14C]glycine; glutamine also markedly decreased the oxidation of L-[U-14C]leucine and [1-14C]glycine in 10-day-old and adult rats.
