an introduction to esters
This page explains what esters are and looks at their simple physical properties such as solubility and boiling points. It includes an introduction to more complicated naturally-occurring esters like animal and vegetable fats and oils.

6 FAQs about [Esters are energy storage substances]
What are esters made of?
Esters can be made from carboxylic acids and alcohols. This is discussed in detail on another page, but in general terms, the two combine together losing a molecule of water in the process. We'll start with a very, very simple ester like ethyl ethanoate - not something complicated like a fat or oil!
Are esters soluble in water?
However, they do not form ester-ester hydrogen bonds, so their boiling points are significantly lower than those of an acid with the same number of carbon atoms. Small esters are fairly soluble in water but solubility decreases with increasing chain length, as shown below:
Why do triglycerides have ester bonds?
In triglycerides, three ester bonds connect three fatty acids to one glycerol molecule, making them an important energy storage form. Phospholipids, which contain ester bonds, are key components of cell membranes, allowing for selective permeability and fluidity.
How do ester bonds affect lipids?
The stability of ester bonds makes them resistant to hydrolysis under normal physiological conditions, but they can be broken down by enzymes called lipases. Ester bonds can affect the physical properties of lipids, such as melting point and solubility, influencing their biological functions and applications.
Why do phospholipids have ester bonds?
Ester bonds are essential in forming phospholipids, which consist of two fatty acids and a phosphate group attached to a glycerol backbone. These bonds allow phospholipids to have both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties, which are critical for forming the bilayer structure of cell membranes.
What is the function of wax esters in prokaryotes?
Their main function is as storage compound for both energy and carbon, yet wax esters may also act as a deposit for toxic or unused FA or as storage of evaporation-resistant lipids in case of desiccation . TAG production in prokaryotes has been suggested to play several roles.
