FATTY ACIDS APEX
The three molecules attached to glycerol backbone are long chain fatty acids.

glycerol
It can be done all in one synthesis. However, there are 3 OHs on glycerol and thus 3 fatty acids required in total to build the triglyceride. There are thus 3 reactions in total that take place but all in one synthesis. This is similar to 3 molecules of NaOH reacting with one molecule of phosphoric acid.
To form a molecule of fat, the two types of molecules that are needed are glycerol and fatty acid. One glycerol molecule attaching itself to three molecules of fatty acid will give one molecule of fat.

Glycerol is a subunit molecule of a lipid. It is a three carbon alcohol that forms the backbone of most lipid molecules in the body.
To form a molecule of fat, the two types of molecules that are needed are glycerol and fatty acid. One glycerol molecule attaching itself to three molecules of fatty acid will give one molecule of fat.
Dehydration synthesis is a generalized form for a condensation reaction. During a condensation reaction, glycerol and 3 fatty acid tails come together to form a triglyceride.
Three water molecules will be removed to form a triglyceride composed of three fatty acid chains and one glycerol molecule. One molecule of water is removed for each bond between a fatty acid and the glycerol molecule, for a total of three water molecules removed.
Subunits of fats are glycerol and fatty acids. Each fat molecule comprises of 1 molecule of glycerol and 3 molecules of fatty acids.
