Galactose and leucine transport in the developing rat small intestine

Jejunal transport of galactose and leucine was studied in 9--45 day-old rats by means of the everted sac technique. Maximum transport was observed in 9--10-day-old rats, but then decreased until the 22nd day, and remained unchanged from then on. There were no remarkable differences in the pattern of galactose and leucine transport over this period.
