Studies by Trypsin Digestion in Vesicle Membranes

Purified adrenocortical microsomal P-450~21 was incorporated into vesicle membranes composed of phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine a t a molar ratio of 5 3 : 1. Trypsinolysis of the incorporated P 4 5 0 ~ ~ ~ resulted in the formation of 30-, 2 5 , and 20-kDa fragments. Similar fragment formation was observed by trypsinolysis of bovine adrenocortical microsome...

Clinical 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 ‘...

Recent 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...
