4. Is the surface of PPO largely hydrophilic or hydrophobic? Based on the surface properties, do you think it would be more soluble in an aqueous environment (e.g. cell cytosol), or in a hydrophobic one (e.g. lipid membrane)? (1 pt)

Answer
The surface of PPO is largely hydrophobic. Based on the surface properties, PPO would be more soluble in a hydrophobic environment such as a lipid membrane.
Solution
a
Hydrophobicity of PPO: The surface properties of PPO (polyphenylene oxide) are largely hydrophobic due to the presence of aromatic rings that do not interact favorably with water
b
Solubility in environments: Given its hydrophobic nature, PPO would be more soluble in hydrophobic environments like lipid membranes rather than in aqueous environments such as cell cytosol
Key Concept
Hydrophobicity and Solubility
Explanation
Molecules with hydrophobic surfaces, like PPO, tend to be more soluble in hydrophobic environments due to the lack of favorable interactions with water.
