Particulate fractions of rat brain catalyze the hydrolysis of radiochemically pure monogalactosyl and digalactosyl diglycerides, which had been synthesized in vifro by enzymes derived from rat brain or spinach chloroplasts. Monogalactosyl-U-W diglyceride (the galactose being uniformly labeled) yields W-galactose when incubated with the mitochondrial fraction of brain at the optimum pH of 4.4 (g...

T w o PATHWAYS have now been described for the biosynthesis of glycerides in mammalian tissues. In the pathway which exists in liver (1, 2) and adipose tissue (3), triglycerides are synthesized from L-a-glycerophosphate via L-a-phosphatidic acids and D-a,@-diglycerides. More recently it has been found that a second pathway involving the direct acylation of monoglyceride exists in intestinal muc...

Bile salts are known to be essential for the effective absorption of fat from the intestinal tract (1). They have been shown to stimulate the action of pancreatic lipase (2) and have an important emulsifying action on water-insoluble dietary triglycerides that is probably related to their ability to form micelles with fatty acids and monoglycerides (3). In addition to their role in triglyceride...

In patients after elective abdominal surgery, different fat emulsions were used to compare their efficacy in total parenteral nutrition and in normalizing plasma lipoprotein levels. In five different groups with 5 patients each, half of the nonprotein calories were given as medium-chain triglycerides/long-chain triglycerides (1:1) or as long-chain triglycerides alone in 10 or 20% fat emulsions ...

1. Epididymal adipose tissues obtained from rats that had been previously starved, starved and refed a high fat diet for 72h, starved and refed bread for 144h or fed a normal diet were incubated in the presence of insulin+glucose or insulin+glucose+acetate. 2. Measurements were made of the whole-tissue concentrations of hexose phosphates, triose phosphates, glycerol 1-phosphate, 3-phosphoglycer...
