What functional feature(s) does the phosphate group contribute to the structure of a phospholipid? select all that apply. select all that apply. nonpolar group that avoids water negative charge to interact with water place to attach fatty acids place where bonds can form between adjoining phospholipids place to attach another small charged molecule?

The phosphate group contribute the following functional features to the structure of phospholipids:
1. Negative charge to interact with water.
2. Place to attach another small molecule. 
The phosphate group is made up of four atoms of oxygen which are attached to one atom of phosphorus. This molecule has a net negative charge of -3. In the phospholipid molecule, the phosphate enhanced the polarity of the phospholipid head by mean of its negative charge which react with water. Phosphate group also provide a point where other small molecules such as alcohol, serine, etc can be attached.
