glycerol molecule造句

• The two components are joined together by a glycerol molecule.
• This means the glycerol molecules and the fatty acid chains begin to break apart.
• Whale oil is mainly composed of triglycerides ( molecules of fatty acids attached to a glycerol molecule ).
• It catalyzes the transfer of a phosphate group from an ATP to a glycerol molecule forming glycerol ( 3 ) phosphate.
• It is made up of a short chain of glycerol molecules connected by ether bonds, with ricinoleic acid side chains connected by ester bonds.
• Here it is converted into glycerol 3-phosphate by the action of glycerol kinase which hydrolyzes one molecule of ATP per glycerol molecule which is phosphorylated.
• However, these glycerol molecules must contribute to the process of glycolysis before they can provide energy to the body, as they do not hold the necessary energy within themselves.
• Looking at the entire glycolysis pathway this conversion would yield an extra ATP for each glycerol molecule that eventually made its way into a DHAP molecule, which demonstrates the benefit of releasing glycerol into the bloodstream.
• When synthesis is complete the free fatty acids are nearly always combined with glycerol ( three fatty acids to one glycerol molecule ) to form triglycerides, the main storage form of fatty acids, and thus of energy in animals.
• The ether linkages make the bonds between phosphate groups and hydrocarbons more stable because the carbon connecting the phosphate group and glycerol molecule is more electron-rich than it would be in an ester, making that carbon less electrophilic and therefore less chemically reactive.
• However, when suffering from a glycerol kinase deficiency many of the glycerol molecules released into the bloodstream end up not being converted to dihydroxyacetone phosphate ( DHAP ), because the host does not have enough of the enzyme to catalyze all of the reactions waiting to occur.
