Multiple Choice
Choose the correct statement about biological waxes:
A
They contain at least one steroid molecule.
B
They are fatty acids bound to long chain alcohol molecules.
C
They are extremely hydrophilic.
D
They are made of 4 fused carbon ring molecules.
Verified step by step guidance1
Begin by understanding what biological waxes are. Biological waxes are a type of lipid, which are hydrophobic molecules primarily composed of carbon and hydrogen atoms.
Next, consider the structure of biological waxes. They are typically composed of long-chain fatty acids esterified to long-chain alcohols. This structure makes them hydrophobic and solid at room temperature.
Evaluate the options given in the problem. The first option mentions steroid molecules, which are not a component of biological waxes. Steroids are a different class of lipids characterized by a structure of four fused carbon rings.
The second option correctly describes biological waxes as fatty acids bound to long-chain alcohol molecules. This matches the typical structure of biological waxes.
The third option states that biological waxes are extremely hydrophilic, which is incorrect. Due to their long hydrocarbon chains, biological waxes are hydrophobic, not hydrophilic.
