Protein Digestion and Absorption
About three-quarters of a century ago, Santayana wrote, "Those who cannot remember the past are condemned to repeat it." This somber dictum is splendidly illustrated by the history of the study of protein digestion and absorption over the same three-quarters of a century (12,13). This chapter begins with a summary of this history, since it provides a deeper understanding of the principles invol...
متن کاملFat Digestion: Intestinal Lipolysis and Product Absorption
Fat digestion in the breastfed newborn infant is a process catalyzed by three Upases. The process is initiated in stomach contents by gastric lipase and continues in the upper part of the small intestine by pancreatic colipase-dependent lipase and human milk bile-salt-stimulated lipase (BSSL). Development of powerful techniques in molecular biology has made it possible to gain better insight in...
متن کاملClinical studies of carbohydrate digestion and absorption.
The reconstituted systems had the same characteristics as the original one. The observations available up to now restrict the choice of the possible mechanisms of the sucrase-dependent sugar-transport system to two. (i) If the hydrolysis is efficiently vectorial, a local hyperconcentration of glucose and fructose may arise which could provide a concentration ‘head’ for an apparently increased ‘...
متن کاملRecent studies of fat digestion and absorption.
HE MECHANISM WHEREBY water-insoluble fat can pass through the intestinal epithelium and into the blood has been a very intriguing as well as a most refractory problem. Obviously, the fat must either pass as particles or it must be solubilized, and various theories have been devised based on both possibilities. Most studies on the degree of hydrolysis of fat during digestion have been undertaken...
متن کاملThe Digestion and Absorption of Triglycerides.
Studies both in vitro and in vivo have established that the hydrolysis of triglycerides in the intestinal tract can yield diglycerides, monoglycerides, free fatty acids, and free glycerol. Thus far it has not been possible to establish which of these materials are absorbed as such into the intestinal wall. That a solution to t.his problem has not been forthcoming was undoubtedly attributable to...
