The Bio-molecule

Our bio-molecule is a Lipid, a lipid mostly contains of fats. Their main biological functions are storing energy, and signalling and acting as a structural component to lipids.


Glycerol is the monomer of the Lipid. It is a simple sugar and alcohol compound.

Triglyceride is the polymer of lipids which derives from glycerol. They are found in you blood and when you eat your body converts unused calories directly into Triglyceride, which are later stored in your fat cells.

Lipid Example

Some example of Lipid's include :

Saturated fat

Unsaturated fat

Monounsaturated fat

Trans fat

Polyunsaturated fat



Bile Salts


Bee's Wax

Ear Wax

Cutin (plant)

Vitamin A,D,E,K

Functional Group

The common Functional Group of a lipid is Hydrocarbon (-O)

Common Functions

The common functions of a lipid include

Chemical messenger

Internal Insulation

Forms part of the cell membrane


Their molecular structure allows many other fatty acid molecules to be fairly close in being connected together. Due to this their molecular interactions give them a high melting point.
