Intestinal uptake and retention of copper in the suckling rat, Rattus rattus--I. Distribution and binding.

Abstract

The distribution of the heterogeneous copper (Cu)-complex in the intestine of the neonatal rat parallels that of total Cu and is maximal in the ileum. In the ileum the total Cu concentration exceeds 400 micrograms/g wet wt at 14 days of age and then falls to about 20 micrograms/g wet wt in the 20-day-old pup. The apoproteins (apopeptides) of the Cu-complex… (More)
