Zinc Uptake by Brush Border Membrane Vesicles (BBMV) from Pre-Weanling Rat Small Intestine

  • Chapter
Trace Elements in Man and Animals 6

Abstract

Zinc (Zn) is required for normal growth and development. To provide for rapid growth, newborn animals absorb Zn to a higher degree than adult animals (1). However, research on the mechanisms behind this observation has been limited. The initial stage of Zn absorption involves transport of Zn across luminal brush border membranes. This process can be specifically investigated (in the absence of cellular and metabolic variables) through isolation of intestinal brush border membrane vesicles (BBMV) (2). Results from studies of Zn uptake into BBMV from various ages of pre-weanling rat pups are presented in this study.
