Describe a hydrophobic tail and a hydrophilic head in a cell membrane. (2 sentences please)

Answer 1

In a cell membrane, a hydrophobic tail consists of long hydrocarbon chains that repel water and are oriented inward, away from the aqueous environment. In contrast, the hydrophilic head contains polar or charged groups that are attracted to water, allowing them to face outward towards the extracellular fluid and intracellular environment, facilitating interactions with the surrounding aqueous environment.
