There are too many functions for lipids.....and many of them are important!
Among many functions, We will discuss three, in my opinion, most important.

Firstly, lipid has a structural function. Our cell membranes are made of lipid. Also, among the cells, the anchoring protein are assist by lipid. if we are lacking in specific lipid, our skin structure will be weaken and inferior to pathogen attack.

Secondly, lipid is store in our body as energy source. Fat is an important metabolic ingredient that will keep us warm in cold weather. In fact, if baby are born without fat, eg, immature early birth, it is very likely that they will die of heat lost!

Finally, lipid is use as chemical signaling in the body, there are many hormones that are lipid base, eg the sex hormones such as estrogen, which play important role in female reproduction!

I hope it is helpful!

The role of lipids in the human body is for energy storage. It produces a great deal of energy upon oxidation and therefore are efficient forms of energy storage. Lipids as mentioned, plays a role in insulation for the body. And also is important for cell membranes. For example Cholesterol is the starting synthesis of all steroid hormones and plays a role in fluidity and increases the permeability to ions...Also Phospholipids (the most abundant membrane lipids) that make up the lipid bilayer of the cell membrane are important to membrane structure as it allows specific molecules to pass across, keeping unwanted substances out- acting as selectively permeable.
