|
It is a very long carbon skeleton with a carboxyl group at one end.
|
|
|
It always consists of C, H, and O in a 1:2:1 ratio.
|
|
|
It consists of a variable R group and an amine group.
|
|
|
It is a 3 carbon compound with hydroxyl on each carbon.

Detailed explanation-1: -Glycerol is a polyol, a compound that contains more than one group of hydroxyls. There are three hydroxyl groups in its chemical structure, which are-OH groups bound to the carbon atoms. Glycerol has 3 Carbon atoms, 3 Oxygen atoms, and 8 Hydrogen atoms.
Detailed explanation-2: -Glycerol is an alcohol with three carbons, five hydrogens, and three hydroxyl (OH) groups. Fatty acids have a long chain of hydrocarbons with a carboxyl group attached and may have 4-36 carbons; however, most of them have 12-18.
Detailed explanation-3: -glycerol is a three-carbon substance that forms the backbone of fatty acids in fats. When the body uses stored fat as a source of energy, glycerol and fatty acids are released into the bloodstream.
Detailed explanation-4: -Glycerol’s molecular formula is C3H8O3. This formula can be written in multiple formats such as CH2OH-CHOH-CH2OH or C3H5(OH)3.
Detailed explanation-5: -In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.
