Fat 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 کاملFat absorption in cystic fibrosis mice is impeded by defective lipolysis and post-lipolytic events.
Cystic fibrosis (CF) is frequently associated with progressive loss of exocrine pancreas function, leading to incomplete digestion and absorption of dietary fat. Supplementing patients with pancreatic lipase reduces fat excretion, but it does not completely correct fat malabsorption, indicating that additional pathological processes affect lipolysis and/or uptake of lipolytic products. To delin...
متن کاملAdipokinetic hormone-induced lipolysis in the fat
The pathway for the adipokinetic hormone-stiniulated synthesis of sn-1,2-diacylglyceroIs in the adult Manducu sexta fat body was studied. Adult fat body lipids were labeled by feeding 5th instar larvae either with [9,10(n)-3H]oleic acid or [ 1 (3)-3H]glycerol and after 32 days insects at the adult stage were used. This long-term prelabeling led to labeled fat body acylglycerols in which triacyl...
متن کاملBile salts and fat absorption.
There has been a recent resurgence of interest in bile salt metabolism. Normally the body contains about 3 g. of bile salts. These comprise conjugates of cholic acid and chenodesoxycholic acid. The free acids are derived from the oxidation of cholesterol in the liver and once formed are conjugated with either taurine or glycine, after which they are secreted into the bile and so enter the small...
متن کاملDisorders of Fat Absorption
I have often been asked how I can keep to so narrow a field as steatorrhoea over a period of years, and my answer has always been that there are so many inviting problems in this field; my main difficulty is really one of confining my energies to a few of them. For instance, there is a wide variety of clinical conditions in which steatorrhoea is seen, often present only as part of a syndrome of...
