Glycerol release

Adipose tissue releases fat by activation of the hormone-sensitive lipase. The glycerol released by adipose tissue can provide some glucose equivalents to the liver. Adipose tissue itself can t use glycerol—it s missing glycerol kinase to make glycerol 3-phosphate. [Pg.230]

Mono-, di- and triacylglycerols may all be measured by determination of the amount of glycerol released by hydrolysis. The lipid is first extracted into chloroform-methanol (2 1) and saponification is performed under conditions that will not affect any phosphate ester bonds, otherwise glycerol originating from phosphoglycerides would also be measured. Heating at 70°C for 30 min with alcoholic potassium hydroxide (0.5 mol l-1) has been shown to be satisfactory. However, the phospholipids may be removed prior to saponification either by extraction or by adsorption on activated silicic acid. [Pg.427]

Hormones can modify the concentration of precursors, particularly the lipolytic hormones (growth hormone, glucagon, adrenaline) and cortisol. The lipolytic hormones stimulate lipolysis in adipose tissue so that they increase glycerol release and the glycerol is then available for gluconeogenesis. Cortisol increases protein degradation in muscle, which increases the release of amino acids (especially glutamine and alanine) from muscle (Chapter 18). [Pg.124]

Not surprisingly, the intake of sufficient carbohydrate to satisfy this demand is vital. If carbohydrate intake is low, glucose is provided in the short term (<24 hours in the adult) by breakdown of liver glycogen. After this period, glucose must be synthesised via the process of gluconeo-genesis primarily from amino acids released from the breakdown of muscle protein and from glycerol released... [Pg.352]

The action of lipoprotein lipase lining the blood vessels degrades the triacyl-glycerols, releasing fatty acids locally for cellular uptake. [Pg.105]

No effect upon spontaneous glycerol release was observed for any drug at this concentration Mean SEM of data from triplicate incubations in three experiments. [Pg.220]

The glycerol released during lipolysis in adipose tissue can be used for the synthesis of TGs or oxidized within the adipose tissue. of these uses would... [Pg.212]
