Matching Properties to Phospholipids and Triglycerides

Steps:

• Identify triglyceride structure: glycerol esterified with three fatty acid chains, making it non-polar and fully hydrophobic.
• Identify phospholipid structure: glycerol with two fatty acid chains and a polar phosphate head, making it amphipathic and partially hydrophobic.
• Assign properties: non-polar to triglyceride, partially hydrophobic to phospholipid.
• Select option matching this assignment: C pairs triglyceride with non-polar and phospholipid with partially hydrophobic.

Why C is correct:

• Triglycerides lack polar groups, rendering them non-polar per their apolar hydrocarbon composition; phospholipids have a hydrophilic head and hydrophobic tails, defining partial hydrophobicity via amphipathicity.

Why the others are wrong:

• A: Lists properties without assigning to specific molecules.
• B: Incorrectly assigns non-polar to phospholipid, which is amphipathic.
• D: Falsely labels both as triglyceride, ignoring distinct structures.

Final answer: C
