WebDietary lipids are hydrolyzed in the intestinal lumen and products are taken up by enterocytes. Enterocytes re-synthesize lipids and package them into chylomicrons for secretion. These lipoproteins are hydrolyzed during circulation and products are taken by peripheral tissues. Remaining remnant particles are removed from circulation by the liver. WebThe diverse structures of sphingolipids elicit various functions in cellular membranes and signal transduction, which may affect cell growth, differentiation, apoptosis, and maintain biological activities. As nutrients, dietary sphingomyelin and its metabolites have wide applications in the food and pharmaceutical industry.
