Which of the following features of phospholipids allows for the phospholipid to interact with the aqueous environment in the extracellular media and the intracellular cytosolic environment?
1. The three-carbon glycenal backbone
2. Fatty acids, attached to the three-carbon glycerol backbone of the phospholipid through ester linkages
3. Phospholipids do not interact with aqueous environments, such as the extracellular between the cell and the aqueous extracellular and intracellular environments O medium or the cytosolic medium. Phospholipids provide a purely hydrophobic barrier
4. The presence of a polar or charged head group attached to the phosphate

Answer:

The correct answer is 4. The presence of a polar or charged head group attached to the phosphate.

Explanation:

Lipids have a hydrophilic head and a hydrophobic tail. This allows them to form structures where the tails are hidden on the inside, and the heads interact with the water molecules. This conformation is the best energetically and allows the lipids to interact with aqueous environments.
