fat
A lipid has three long chains of fatty acids and one molecule of glycerol
The general equation for the hydrolysis of a lipid molecule is: Lipid + water → fatty acid(s) + glycerol
The lipid tails of a phospholipid molecule are hydrophobic, as they consist of nonpolar fatty acid chains that repel water.
Three fatty acid molecules can combine with one glycerol molecule in a lipid synthesis reaction to form a triacylglycerol molecule. Each of the three hydroxyl groups of glycerol can form an ester bond with a fatty acid molecule.
Hydrolysis is the process wherein a covalent bond within a molecule is broken down. A water molecule is used up in the process (hydro=water;lysis=cut/sever) Usually the process results in one of the reaction products having a Hydrogen atom where the bond used to be, and the other having a hydroxyl group (-OH, also known as an alcohol) In the case of lipids, the molecule itself consists of a glycerol backbone bonded to three long chain fatty acids. Hydrolysis of the lipid results in breaking the fatty acids off, leaving free fatty acids and a glycerol molecule, and using up three water molecules. This process can be catalyzed under acidic or basic conditions, and is actually how soap is made. Reacting the free fatty acids with some ionic salts actually gives you soap. The left over glycerol is more commonly known as glycerine, which is itself found in a great many products.

The monomer for a lipid would be 3 fatty acids and a glycerol molecule.

The lipid was most likely a fat, as fats are made up of triglycerides containing three fatty acid chains and a glycerol molecule. When hydrolyzed, fats break down into fatty acids and glycerol. Oils, on the other hand, are usually liquid at room temperature and are also composed of triglycerides.

A lipid that cannot be hydrolyzed is called a wax. Waxes are esters of long-chain fatty acids with long-chain alcohols and are resistant to hydrolysis due to their structure. They are commonly found in plants and animals for protective purposes.
