A sweet viscous fluid obtained by the saponification of fats and fixed oils; used as a solvent, as a skin emollient, by injection or in the form of suppository for constipation, and as a vehicle and sweetening agent.
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.
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.
Etymology: Gk, glykys, sweet
an alcohol that is a component of fats. Glycerol is soluble in ethyl alcohol and water. Also called 1, 2, 3-propanetriol. See also glycerin.
A sweet oily fluid obtained by the saponification of fats and fixed oils; used as a solvent, as a skin emollient, by injection or in suppository form for constipation, orally to reduce ocular tension, and as a vehicle and sweetening agent.
glycerina 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.
glycerolthree-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; glycerin pig fat-derived fluid, used as a solvent or an emollient
glyc·er·ol, glycerin (glis'ĕr-ol, -in)
A sweet viscous fluid obtained by the saponification of fats and fixed oils; used as a solvent, as a skin emollient, by injection or in the form of suppository for constipation, and as a sweetener.
n.pr an alcohol that is a component of fats. See also glycerin.
a trihydric sugar alcohol, CH2OH⋅CHOH⋅CH2OH, which is a component of triglycerides. Pharmaceutical preparations are called glycerin.
see glyceryl guaiacolate.
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.
