Satiety means an internal state that leads to termination of eating. We have isolated an anorexigenic glycoprotein (M.W. 50,000 dalton) from human and rat erythrocyte membrane and from rat liver plasma membrane. The substance isolated from all these membrane sources has almost same onset and offset anorectic effect in rats deprived of food for 96 h as well as in normally fed rats without any rebound. Similar properties of membrane anorectic substance and plasma satietin indicated that it has membrane origin. The results also suggest that the loss of appetite in chronic diseases involving damage or turn-over of cell membranes could be due to release of a glycopeptide from cellular membranes into the circulation.
