lipid
The molecule is a fatty acid called dodecanoic acid or lauric acid. It belongs to the carboxylic acid group and is commonly found in coconut oil.
This kind of molecule is called a fatty acid. Fatty acids are comprised of a hydrocarbon chain with a carboxyl group at one end, which makes them amphiphilic molecules important for cellular structure and energy storage.
A triglyceride will give a single molecule of fatty acid when hydrolyzed through the process of lipolysis. Triglycerides consist of three fatty acid molecules attached to a glycerol molecule. Upon hydrolysis, one fatty acid is released along with glycerol.
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.
One glycerol molecule and three fatty acid molecule
Three water molecules are formed when a glycerol molecule combines with three fatty acid molecules in a condensation reaction. Each fatty acid molecule contributes a water molecule when it reacts with the glycerol molecule to form a triglyceride.
A triglyceride with one fatty acid bound to a glycerol backbone has a structure where the fatty acid is attached to one of the three hydroxyl groups on the glycerol molecule. This forms an ester bond between the fatty acid and the glycerol, creating a molecule with a glycerol backbone and one fatty acid chain attached.
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.
This is called the hydrophobic 'side' of the phospholipid molecule
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.
A triglyceride molecule has 3 fatty acid tails attached to a glycerol backbone, and these fatty acid tails can be either saturated or unsaturated depending on the presence of double bonds in the hydrocarbon chain.
Fat is a fairly complicated compound: it is composed of a glycerin molecule with 3 fatty acid molecules attached. Each of the fatty acid molecules is composed of a carboxylic acid molecule and a hydrocarbon polymer molecule chain. The hydrocarbon polymer molecule chains can be of any length and either flexible or rigid. The hydrocarbon polymer molecule chains will likely be different in each of the 3 fatty acid molecules in a given fat molecule.
