In the mature human newborn infant, only pancreatic alpha-amylase shows a very low but highly inducible activity. Other digestive enzymes, although not yet at adult levels, increase rapidly with age. Intestinal absorptive functions develop already during early and mid-pregnancy and are mostly at adult levels in the newborn infant. Fat absorption is usually low in the premature infant and increases rapidly during the first month.
