ABSTRACT
Myristic, palmitic, stearic, oleic and linoleic acids have been identified as the covalently bound fatty acids in the monkey gastrointestinal mucosal membrane proteins and among them palmitolation was predominant. Distribution studies in various regions of the gastrointestinal mucosa showed no significant difference in the content and composition of covalently bound fatty acids in these membrane and most of the fatty acids were found to be ester linked. Total membranes from isolated crypt and villus enterocytes and colonocytes had similar composition of these fatty acids. Covalently bound fatty acid levels were higher in the small intestinal brush border membrane. As suggested for the mucus glycoproteins, covalently bound fatty acids in the intestinal epithelial cell membrane may protect these membranes from proteolytic damage from the luminal proteases.
