What might be characteristic features of the phospholipid head groups? What might be characteristic features of the phospholipid head groups? The phospholipid head groups would likely bind to each other with hydrogen bonding that would pack well and not be bulky. The phospholipid head groups would likely bind to each other with covalent bonds that would pack well and not be bulky. The phospholipid head groups would likely have equal numbers of hydroxyl and amino groups that would pack well and not be bulky. The phospholipid head groups would likely have equal numbers of positively and negatively charged groups that would pack well and not be bulky.

The best answer to the question: What might be a characteristic features of the phospholipid head groups? Would be: The phospholipid head groups would likely bind to each other with hydrogen bonding that would pack well and not be bulky.

Explanation:

Phospholipids are the main molecules in biomembranes. Because of their importance to cell membrane formation, phospholipids are very characteristic molecules that have two sides: one polar and hydrophilic, and one non-polar and hydrophobic. The hydrophilic side is really vital, as biomembranes, like cell membranes, are suspended in water, and therefore need to interact with it. But these phospholipids form a structure called a bilayer, meaning, it forms a sort of highly organized lattice (called a leaflet), that has two hydrophilic sides (where the heads of the phospholipids lie) and a middle that is hydrophobic (where the tails are). The perfect interaction of phospholipids with water comes from their unique polar charges in their phosphate groups, which are present in the head side (hydrophilic side) and which form ionic and hydrogen bonds with each other and water. This characteristic provides stability to the structure and permits it to carry out its function with both the outer and inner environments of cells.
