Question

multiple choice question
molecules that are water-loving, like the polar heads of a phospholipid, are said to be;
○ hydrophilic
○ hydrophobic
○ glycolipids
○ glycoproteins

Explanation:

To solve this, we analyze each option:

• Hydrophilic: Means "water - loving" (from Greek "hydro" for water and "philic" for loving). Polar molecules, like the polar heads of phospholipids, interact favorably with water, so this fits.
• Hydrophobic: Means "water - fearing" and repels water, so it's incorrect.
• Glycolipids: These are lipids with carbohydrate groups, not a term for water - loving molecules, so incorrect.
• Glycoproteins: These are proteins with carbohydrate groups, not a term for water - loving molecules, so incorrect.

Answer:

A. hydrophilic
