That was for the character limit thing!

Answer:

Phosphate group.

Explanation:

One of the form of lipids is triglycerides.

Triglycerides are the lipids which have one glycerol molecule bonded with three fatty acid chains, so it is a triester of glycerol hence known as triglycerides.

In case of phospholipids also there is a glycerol molecule to which two fatty acids are bonded and in place of third fatty acid it has a phosphate group which makes it different from other lipids or triglycerides.
