The Metabolism of Glyceride Glycolipids

The metabolism of glyceride glycolipids. IV. Enzymatic hydrolysis of monogalactosyl and digalactosyl diglycerides in rat brain.

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...

The metabolism of glyceride-glycerol.

Various aspects of glycerol metabolism have been extensively investigated, both in vivo and in vitro, with the aid of isotopic glycerol. Experiments in vivo on the incorporation of C14-glycerol into glycogen and various body lipides, as well as its oxidation to C1402 have been reported (l-3). The metabolism of Ci4-glycerol by liver in vitro (4) and glycogen synthesis from deuterium-labeled glyc...

Cxxx. the Glyceride Structure of Beef

Control of hepatic glyceride synthesis.

Role of the liver in glyceride metabolism In mammals, there are three major forms of circulating lipid or lipid-related fuel, free fatty acid (FFA), triglyceride (TG) and ketone bodies. The liver utilizes FFA, and releases T G and ketone bodies. Constituents of the pool of carbohydrate plus amino acids can undergo net conversion to acetyl residues and then to fatty acids (FA) (FA synthesis ‘de ...

Pathways of glyceride glycerol synthesis.

Isolated rat liver parenchymal cells were incubated for various periods with [U-(14)C,2-(3)H]glycerol and the radioisotopic yields in the major products were determined, as well as the (3)H/(14)C ratios in glyceride glycerol and intracellular glycerol phosphate. Under the conditions used (0.1mm-glycerol+10mm-l-lactate or 10mm-glycerol as substrates), only small differences were found between th...
