Abstract
Studies on the surface area of microvilli (MV), fluidity of brush border membranes (BBM) and d‐glucose uptake were carried out in rat intestinal epithelial cells (IEC) during progressive starvation and under re‐feed conditions. The surface area of MV, fluidity of BBM and d‐glucose transport through IEC membranes showed an increase during starvation when compared to well‐fed controls. Re‐feeding experiments restored the control values of all the three parameters within a short time. The results showed that the increase in d‐glucose transport through IEC membranes during starvation is due to increased surface area of MV and increased fluidity of BBM.Keywords
