glycerol

/glyc·er·ol/ (-ol) a trihydroxy sugar alcohol that is the backbone of many lipids and an important intermediate in carbohydrate and lipid metabolism. Pharmaceutical preparations are called glycerin.

n.
A syrupy, sweet, colorless or yellowish liquid triol, C3H8O3, obtained from fats and oils as a byproduct of saponification and used as a solvent, antifreeze, plasticizer, and sweetener and in the manufacture of dynamite, cosmetics, liquid soaps, inks, and lubricants.

glycerol

glycerin

a simple LIPID that is a basic component of fats. See Fig. 174 . Glycerol contains high amounts of energy which can be released in metabolism. see GLYCOLYSIS.

glycerol

three-carbon carbohydrate; known as the 'backbone of triacylglycerol'. Blood glycerol concentration mainly depends on the rate of lipolysis of triglycerides in adipose tissue. Glycerol is an important source of glucose during periods of fasting or starvation. In sport, consumption of glycerol may be used for hyperhydration, as it reduces renal water clearance, increasing fluid retention and total body water. See also gluconeogenesis, hydration status.

glycerol 3-phosphate dehydrogenase
two enzymes, an NAD+-dependent form in the cytosol and an FAD-dependent form present in the inner mitochondrial membrane. These two enzymes complete the transfer of reducing power generated as NADH+H+ during glycolysis through to FADH2 which can enter complex II of the oxidative phosphorylation sequence. This process is called the glycerophosphate shuttle.
glycerol phosphate shuttle
main means for the transfer of reducing power generated in the cytosol as NADH+H+ to the mitochondrion as FADH2 so that ATP can be generated in oxidative phosphorylation. There is the loss of one potential ATP as a consequence of this shuttle. Commonly found in the brain.
